Check Digit Verification of cas no

The CAS Registry Mumber 1438253-40-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,8,2,5 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1438253-40:
(9*1)+(8*4)+(7*3)+(6*8)+(5*2)+(4*5)+(3*3)+(2*4)+(1*0)=157
157 % 10 = 7
So 1438253-40-7 is a valid CAS Registry Number.

New approach to oximes through reduction of nitro compounds enabled by visible light photoredox catalysis

Cai, Shunyou,Zhang, Shaolong,Zhao, Yaohong,Wang, David Zhigang

, p. 2660 - 2663 (2013/07/11)

A range of nitro compounds are smoothly reduced to their corresponding oximes under the synergistic effects of visible light irradiation, the Ru(bpy)3Cl2 photocatalyst, Hünig's base, Mg(ClO 4)2 activation, and MeCN solvent. This remarkably mild and environmentally benign protocol, when orchestrated with classical Beckmann rearrangement, enables such high-value industrial feedstock as caprolactam to be readily accessed from simple precursor nitrocyclohexane.
