Check Digit Verification of cas no
The CAS Registry Mumber 136981-91-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,9,8 and 1 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 136981-91:
(8*1)+(7*3)+(6*6)+(5*9)+(4*8)+(3*1)+(2*9)+(1*1)=164
164 % 10 = 4
So 136981-91-4 is a valid CAS Registry Number.

Peroxidation of saccharide phenylhydrazones
El Khadem,Crossman Jr.,Bensen
, p. 9 - 11,c9-c11 (2007/10/02)
It is known that phenylhydrazones undergo autooxidation by free-radical mechanism to afford phenylazo-hydroperoxides of the type H-O-O-CH-N=N-Ph. Also saccharide phenylhydrazones subjected to oxygen in the presence of bases produce free radicals detectabl
