Check Digit Verification of cas no

The CAS Registry Mumber 858-98-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,5 and 8 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 858-98:
(5*8)+(4*5)+(3*8)+(2*9)+(1*8)=110
110 % 10 = 0
So 858-98-0 is a valid CAS Registry Number.

Synthesis of Various Bridged Ring Systems via Rhodium-Catalyzed Bridged (3+2) Cycloadditions

He, Yu-Tao,Li, Li-Xuan,Lin, Xiaohong,Hou, Bao-Long,Li, Chuang-Chuang

supporting information, p. 186 - 190 (2022/01/11)

Here, we describe the rhodium-catalyzed bridged (3+2) cycloaddition cascade reactions of N-sulfonyl-1,2,3-triazoles, which allowed the efficient diastereoselective construction of various functionalized and synthetically challenging bridged ring systems. This simple, direct transformation had a broad substrate scope and excellent functional group tolerance. The highly strained polycyclic bicyclo[2.2.2]octa[b]indole core of fruticosine was synthesized efficiently using this methodology.

Stereoselective Dehydroxyboration of Allylic Alcohols to Access (E)-Allylboronates by a Combination of C-OH Cleavage and Boron Transfer under Iron Catalysis

Su, Wei,Wang, Ting-Ting,Tian, Xia,Han, Jian-Rong,Zhen, Xiao-Li,Fan, Shi-Ming,You, Ya-Xin,Zhang, Yu-Kun,Qiao, Rui-Xiao,Cheng, Qiushi,Liu, Shouxin

supporting information, p. 9094 - 9099 (2021/11/30)

Iron-catalyzed direct SN2′ dehydroxyboration of allylic alcohols has been developed to access (E)-stereoselective allylboronates. Allylic alcohols with diverse structures and functional groups, especially derived from natural products, underwent smooth transformation. The six-membered ring transition state formed by allylic alcohols and iron-boron intermediate was indicated to be the key component involved in transfer of the boron group, activation of the C-OH bond, and control of the stereoselectivity.

Design and synthesis of dansyl-labeled inhibitors of steroid sulfatase for optical imaging

Barbeau, Xavier,Lambert, Jean-Philippe,Ngueta Djiemeny, Adrien,Poirier, Donald,Roy, Jenny,Maltais, René

, (2020/03/05)

Steroid sulfatase (STS) is an important enzyme regulating the conversion of sulfated steroids into their active hydroxylated forms. Notably, the inhibition of STS has been shown to decrease the levels of active estrogens and was translated into clinical t
