Check Digit Verification of cas no

The CAS Registry Mumber 69830-91-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,8,3 and 0 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 69830-91:
(7*6)+(6*9)+(5*8)+(4*3)+(3*0)+(2*9)+(1*1)=167
167 % 10 = 7
So 69830-91-7 is a valid CAS Registry Number.

Stereoselective synthesis of chiral δ-lactonesviaan engineered carbonyl reductase

Wang, Tao,Zhang, Xiao-Yan,Zheng, Yu-Cong,Bai, Yun-Peng

, p. 10584 - 10587 (2021/10/19)

A carbonyl reductase variant,SmCRM5, fromSerratia marcescenswas obtained through structure-guided directed evolution. The variant showed improved specific activity (U mg?1) towards most of the 16 tested substrates and gave high stereoselectivities of up to 99% in the asymmetric synthesis of 13 γ-/δ-lactones. In particular, SmCRM5showed a 13.8-fold higher specific activity towards the model substrate,i.e., 5-oxodecanoic acid, and gave (R)-δ-decalactone in 99% ee with a space-time yield (STY) of 301 g L?1d?1. The preparative synthesis of six δ-lactones in high yields and with high enantiopurities showed the feasibility of the biocatalytic synthesis of these high-value-added chemicals, providing a cost-effective and green alternative to noble-metal catalysis.

Efficient Stereoselective Synthesis of Structurally Diverse γ- and δ-Lactones Using an Engineered Carbonyl Reductase

Chen, Meng,Zhang, Xiao-Yan,Xing, Chen-Guang,Zhang, Chao,Zheng, Yu-Cong,Pan, Jiang,Xu, Jian-He,Bai, Yun-Peng

, p. 2600 - 2606 (2019/05/21)

Structurally diverse γ- and δ-lactones were efficiently synthesized stereoselectively using an engineered carbonyl reductase from Serratia marcescens (SmCRV4). SmCRV4 exhibited improved activity (up to 500-fold) and thermostability toward 14 γ-/δ-keto acids and esters, compared with the wild-type enzyme, with 110-fold enhancement in catalytic efficiency (kcat/Km) toward methyl 4-oxodecanoate. The preparative synthesis of alkyl and aromatic γ- and δ-lactones with 95 %–>99 % ee and 78 %–90 % yields was demonstrated. The highest space-time yield, 1175 g L?1 d?1, was achieved for (R)-γ-decalactone.

Diastereo- and Enantioselective Synthesis of (E)-δ-Boryl-Substituted anti-Homoallylic Alcohols in Two Steps from Terminal Alkynes

Miura, Tomoya,Oku, Naoki,Murakami, Masahiro

supporting information, p. 14620 - 14624 (2019/09/06)

We report the highly diastereo- and enantioselective preparation of (E)-δ-boryl-substituted anti-homoallylic alcohols in two steps from terminal alkynes. This method consists of a cobalt(II)-catalyzed 1,1-diboration reaction of terminal alkynes with B2pin2 and a palladium(I)-mediated asymmetric allylation reaction of the resulting 1,1-di(boryl)alk-1-enes with aldehydes in the presence of a chiral phosphoric acid. Propyne, which is produced as the byproduct during petroleum refining, could be used as the starting material to construct homoallylic alcohols that are otherwise difficult to synthesize with high stereocontrol.
