Check Digit Verification of cas no

The CAS Registry Mumber 187344-92-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,7,3,4 and 4 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 187344-92:
(8*1)+(7*8)+(6*7)+(5*3)+(4*4)+(3*4)+(2*9)+(1*2)=169
169 % 10 = 9
So 187344-92-9 is a valid CAS Registry Number.

Synthesis of novel C2 and C1 symmetric chiraphos derivatives and their application in palladium-catalyzed miyauramichael reaction

Jin, Masayoshi,Nakamura, Masaharu

, p. 1035 - 1037 (2013)

A new method for the synthesis of C2 and C1 symmetric CHIRAPHOS derivatives and their application in Pd-catalyzed 1,4-addition reaction of an aryl boron compound to an ,¢-unsaturated carbonyl compound (MiyauraMichael reaction) are described. Six CHIRAPHOS congeners are prepared by substitution reactions of (2R,3R)-butane-2,3-diyl ditosylate with metalated phosphineborane adducts and subsequent deprotection of the resulting borane-protected bisphosphines. In the asymmetric MiyauraMichael reaction, the CHIRAPHOS derivative containing 4-tolyl groups showed a higher enantioselectivity than the others including parent CHIRAPHOS.

Paragraph 0085-0088; 0093-0096; 0128-0129; 0134-0135; ..., (2021/12/31)

The invention belongs to the field of organic chemical ligands, and particularly relates to a cinchona alkali ligand, which has a structure shown in a general formula I or a tautomer, an enantiomer and a diastereoisomer thereof, in the formula I, R1 is selected from alkyl, alkenyl and -CH = CHPh, R2 is selected from hydrogen, alkyl, phenyl and substituted phenyl, and R is selected from substituted phenyl. The invention also discloses a preparation method and application of the cinchona alkaloid ligand. The ligand disclosed by the invention has advantages in stereoselectivity and reaction efficiency, and a higher ee value and yield can be obtained in an asymmetric reaction.

Highly Enantioselective Synthesis of Phosphorus-Containing ?-Benzosultams by Bifunctional Phosphonium Salt-Promoted Hydrophosphonylation

Zhang, Song,Feng, Zhenghuai,Jiang, Chunhui,Yu, Xiaojun,Pan, Jianke,Du, Juan,Jiang, Zhiyu,Chen, Yuan,Wang, Tianli

supporting information, p. 11285 - 11290 (2021/07/02)

?-Benzosultam derivatives are potential drug candidates with diverse biological activities. A series of chiral ?-benzosultams bearing phosphorus functionalities was synthesized by catalytic asymmetric hydrophosphonylation in the presence of a bifunctional phosphonium salt catalyst. The desired hydrophosphonylation products were obtained in good yields with high enantioselectivities, and scale-up reactions and further derivations were successfully accomplished. Some control experiments were also conducted to elucidate the plausible reaction mechanism of this chemical transformation.
