Check Digit Verification of cas no

The CAS Registry Mumber 1616399-34-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,6,3,9 and 9 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1616399-34:
(9*1)+(8*6)+(7*1)+(6*6)+(5*3)+(4*9)+(3*9)+(2*3)+(1*4)=188
188 % 10 = 8
So 1616399-34-8 is a valid CAS Registry Number.

Chiral Co(II) complex catalyzed asymmetric Michael reactions of β-ketoamides to nitroolefins and alkynones

Zhang, Zuliang,Liu, Xiaohua,Wang, Zhen,Zhao, Xiaohu,Lin, Lili,Feng, Xiaoming

, p. 3797 - 3801 (2014)

The catalytic enantioselective Michael additions of cyclic β-ketoamides to nitroolefins and alkynones were accomplished in the presence of chiral N,N′-dioxide-Co(II) complexes. The desired adducts were obtained in high yields (up to 98%) with excellent en
