Check Digit Verification of cas no

The CAS Registry Mumber 1263575-72-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,3,5,7 and 5 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1263575-72:
(9*1)+(8*2)+(7*6)+(6*3)+(5*5)+(4*7)+(3*5)+(2*7)+(1*2)=169
169 % 10 = 9
So 1263575-72-9 is a valid CAS Registry Number.

Asymmetric α-amination of 4-substituted pyrazolones catalyzed by a chiral Gd(OTf)3/ N,N′-dioxide complex: Highly enantioselective synthesis of 4-amino-5-pyrazolone derivatives

Yang, Zhigang,Wang, Zhen,Bai, Sha,Liu, Xiaohua,Lin, Lili,Feng, Xiaoming

supporting information; experimental part, p. 596 - 599 (2011/04/15)

The asymmetric α-amination of 4-substituted pyrazolones with azodicarboxylates was investigated for the first time, employing an N,N′-dioxide gadolinium(III) complex as the catalyst. The novel transformations exhibited high yield, and 4-amino-5-pyrazolone
