Check Digit Verification of cas no

The CAS Registry Mumber 1449604-87-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,9,6,0 and 4 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1449604-87:
(9*1)+(8*4)+(7*4)+(6*9)+(5*6)+(4*0)+(3*4)+(2*8)+(1*7)=188
188 % 10 = 8
So 1449604-87-8 is a valid CAS Registry Number.

Chiral squaramide catalyzed asymmetric conjugate additions of 3-substituted oxindoles to vinylphosphonates

Duan, Shu-Wen,Liu, Yi-Yin,Ding, Wei,Li, Tian-Ren,Shi, De-Qing,Chen, Jia-Rong,Xiao, Wen-Jing

, p. 1647 - 1653 (2013/07/27)

An efficient organocatalytic enantioselective conjugate addition of 3-substituted oxindoles to activated vinylphosphonates has been described. This reaction allows the facile synthesis of a new family of organophosphorus derivatives bearing an oxindole motif in high chemical yields with good to excellent stereoselectivities.
