Check Digit Verification of cas no

The CAS Registry Mumber 1537899-25-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,3,7,8,9 and 9 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1537899-25:
(9*1)+(8*5)+(7*3)+(6*7)+(5*8)+(4*9)+(3*9)+(2*2)+(1*5)=224
224 % 10 = 4
So 1537899-25-4 is a valid CAS Registry Number.

Highly enantioselective organocatalytic α-sulfenylation of azlactones

Qiao, Baokun,Liu, Xinfei,Duan, Shaobo,Yan, Lin,Jiang, Zhiyong

supporting information, p. 672 - 675 (2014/03/21)

The first asymmetric α-sulfenylation of azlactones with N-(sulfanyl)succinimides has been developed by using cinchona alkaloid-derived squaramide as a catalyst and 4 A molecular sieves as an additive. The reaction conditions were suitable to 4-alkyl and benzyl-substituted azlactones as well as N-(benzyl/alkyl/arylthio)succinimides, affording adducts with high enantioselectivities (81-94% ee).
