Check Digit Verification of cas no

The CAS Registry Mumber 1353155-79-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,3,1,5 and 5 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1353155-79:
(9*1)+(8*3)+(7*5)+(6*3)+(5*1)+(4*5)+(3*5)+(2*7)+(1*9)=149
149 % 10 = 9
So 1353155-79-9 is a valid CAS Registry Number.

Expeditious diastereoselective construction of a thiochroman skeleton via a cinchona alkaloid-derived catalyst

Du, Zhiyun,Zhou, Chenggang,Gao, Yaojun,Ren, Qiao,Zhang, Kun,Cheng, Hansong,Wang, Wei,Wang, Jian

supporting information; experimental part, p. 36 - 39 (2012/01/06)

An example of diastereoselective and enantioselective synthesis of thiochroman derivatives through a sulfa-Michael-Michael cascade sequence is disclosed. This is a significant complement of the quinine-thiourea catalyzed sulfa-Michael-Michael cascade reaction. The densely functionalized target thiochromans were obtained in high diastereoselectivities, and with high to excellent enantioselectivities.
