Check Digit Verification of cas no

The CAS Registry Mumber 1489240-28-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,8,9,2,4 and 0 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1489240-28:
(9*1)+(8*4)+(7*8)+(6*9)+(5*2)+(4*4)+(3*0)+(2*2)+(1*8)=189
189 % 10 = 9
So 1489240-28-9 is a valid CAS Registry Number.

Asymmetric Mannich Reaction and Construction of Axially Chiral Sulfone-Containing Styrenes in One Pot from α-Amido Sulfones Based on the Waste-Reuse Strategy

Li, Dongmei,Tan, Yu,Peng, Lei,Li, Shan,Zhang, Nan,Liu, Yidong,Yan, Hailong

, p. 4959 - 4963 (2018)

A simultaneous asymmetric Mannich reaction and the construction of axially chiral sulfone-containing styrenes in one pot from α-amido sulfones based on the waste-reuse strategy was demonstrated. A series of chiral β-amino diesters and axially chiral sulfone-containing styrenes with various functional groups were synthesized in good to excellent yields and enantioselectivities under mild conditions. In addition, this protocol has been successfully applied to synthesize the anti-HIV drug Maraviroc and chiral trichloro derivatives.
