Check Digit Verification of cas no

The CAS Registry Mumber 857595-49-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,7,5,9 and 5 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 857595-49:
(8*8)+(7*5)+(6*7)+(5*5)+(4*9)+(3*5)+(2*4)+(1*9)=234
234 % 10 = 4
So 857595-49-4 is a valid CAS Registry Number.

Photoinduced cleavage of N-N bonds of aromatic hydrazines and hydrazides by visible light

Zhu, Mingzhao,Zheng, Nan

, p. 2223 - 2236 (2011)

A photocatalytic system involving [Ru(bpyrz)(PFH, visible light, and air has been developed for cleavage of the N-N bonds of hydrazines and hydrazides. This catalytic system is generally effective for N,N-disubstituted hydrazine and hydrazide derivatives, including arylhydrazides, N-alkyl-N-arylhydrazines, and N,N-diarylhydrazines. The utility of this cleavage reaction has been demonstrated by synthesizing a variety of secondary aromatic amines. Georg Thieme Verlag Stuttgart ? New York.
