Check Digit Verification of cas no

The CAS Registry Mumber 1260605-71-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,0,6,0 and 5 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1260605-71:
(9*1)+(8*2)+(7*6)+(6*0)+(5*6)+(4*0)+(3*5)+(2*7)+(1*1)=127
127 % 10 = 7
So 1260605-71-7 is a valid CAS Registry Number.

Enantioselective biomimetic transamination of α-keto acids catalyzed by H4-naphthalene-derived axially chiral biaryl pyridoxamines

Hou, Chengkang,Zhao, Guoqing,Xu, Dongfang,Zhao, Baoguo

supporting information, p. 1028 - 1033 (2018/02/15)

Asymmetric biomimetic transamination is a highly attractive method for synthesis of chemically and biologically important chiral amino acids and chiral amines. Development of chiral pyridoxamines/pyridoxals is the key for the reaction. New axially chiral biaryl pyridoxamines based on H4-naphathene skeleton have been developed. The pyridoxamines display good enantioselectivity and high catalytic activity in asymmetric biomimetic transamination of α-keto acids, affording various optically active unnatural amino acids in 61–98% yields with up to 91% ee's.

Asymmetric Transamination of α-Keto Acids Catalyzed by Chiral Pyridoxamines

Lan, Xiaoyu,Tao, Chuangan,Liu, Xuliang,Zhang, Aina,Zhao, Baoguo

supporting information, p. 3658 - 3661 (2016/08/16)

A new type of novel chiral pyridoxamines 3a-g containing a side chain has been developed. The pyridoxamines displayed catalytic activity and promising enantioselectivity in biomimetic asymmetric transamination of α-keto acids, to give various α-amino acids in 47-90% yields with up to 87% ee's under very mild conditions. An interesting effect of the side chain on enantioselectivity was observed in the reaction.
