Check Digit Verification of cas no

The CAS Registry Mumber 37067-45-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,7,0,6 and 7 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 37067-45:
(7*3)+(6*7)+(5*0)+(4*6)+(3*7)+(2*4)+(1*5)=121
121 % 10 = 1
So 37067-45-1 is a valid CAS Registry Number.

Hydrazidines, V. - Synthesis and Reactions of Aromatic and Aliphatic Hydrazidines and Their N1-Substituted Derivatives

Neunhoeffer, Hans,Karafiat, Ute,Koehler, Gernot,Sowa, Birgit

, p. 115 - 126 (2007/10/02)

Aromatic hydrazidines 3 have been synthetized by reaction of aromatic orthocarboxylates 4 with tert-butyl carbazate (5) and reaction of the protected hydrazidines 7 with HCl/methanol or HBr/acetic acid.Aliphatic N1-methylhydrazidines 8 have been prepared by methylation of bis (tert-butoxycarbonyl)-hydrazidines 7 and deprotection with HBr/acetic acid.Aromatic N1-methylhydrazidines 8 have been obtained by methylation of N1-methyl(thiohydrazides) 11, reaction of 12 with tert-butyl carbazate (5) and deprotection of 13 with HCl/methanol. -- Attempts to remove both protecting groups in N1-alkyl-N2,N4-bis(benzylidene)hydrazidines 16 failed. -- Some reactions of 3 and 8 are described.Key Words: Hydrazidines / 1,2,4-Triazines / 1,2,4,5-Tetrazines / 1,2,4,5-Tetrazinoisoindoles / Pyrrolo1,2,4,5-tetrazines
