Check Digit Verification of cas no

The CAS Registry Mumber 219593-28-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,5,9 and 3 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 219593-28:
(8*2)+(7*1)+(6*9)+(5*5)+(4*9)+(3*3)+(2*2)+(1*8)=159
159 % 10 = 9
So 219593-28-9 is a valid CAS Registry Number.

Salan-vanadium catalyzed enantioselective desymmetrization of meso-epoxides with aromatic thiols

Sun, Jiangtao,Gu, Weijin,Huang, Yijun,Pan, Xu,Zhu, Chengjian

, p. 329 - 331 (2009)

The first example of salan-vanadium catalyzed enantioselective ring-opening of meso-epoxides has been reported, which furnished β-hydroxy sulfides in good yields and moderate enantioselectivities.

Catalytic asymmetric ring-opening reaction of meso-epoxides with aryl selenols and thiols catalyzed by a heterobimetallic gallium-titanium-salen complex

Sun, Jiangtao,Yang, Minghua,Yuan, Fang,Jia, Xuefeng,Yang, Xia,Pan, Yi,Zhu, Chengjian

supporting information; experimental part, p. 920 - 930 (2009/11/30)

A chiral heterobimetallic Lewis acid complex has been developed as an efficient catalyst. The enantioselective desymmetrization of meso-epoxides with aryl selenols and thiols catalyzed by the heterobimetallic complex has been optimized. The optically active β-arylseleno alcohols and β-hydroxy sulfides were obtained in good yields and high enantioselec- tivities (up to 97% ee and 92% ee, respectively). A strong synergistic effect between different Lewis acids was exhibited in the catalytic process. & copy; 2009 Wiley-VCH Verlag GmbH & Co. KGaA.

Enantioselective ring-opening reaction of meso-epoxides with ArSH catalyzed by heterobimetallic Ti-Ga-Salen system

Sun, Jiangtao,Yuan, Fang,Yang, Minghua,Pan, Yi,Zhu, Chengjian

experimental part, p. 548 - 551 (2009/04/14)

The enantioselective ring-opening reaction of meso-epoxides with aryl thiols catalyzed by a chiral heterobimetallic Ti-Ga-Salen complex was realized, and the 1,2-mercapto alcohols were obtained in good yields and moderate to high enantioselectivities (up
