Check Digit Verification of cas no

The CAS Registry Mumber 91658-54-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,6,5 and 8 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 91658-54:
(7*9)+(6*1)+(5*6)+(4*5)+(3*8)+(2*5)+(1*4)=157
157 % 10 = 7
So 91658-54-7 is a valid CAS Registry Number.

TETRAZOLES. ACYLATION OF TETRAZOLES UNDER THE CONDITIONS OF PHASE-TRANSFER CATALYSIS

Osipova, T. F.,Koldobskii, G. I.,Ostrovskii, V. A.

, p. 2248 - 2252 (2007/10/02)

The acylation of substituted 5-aryltetrazoles with benzoyl chloride in the presence of tetrabutylammonium bromide in the two-phase methylene chloride-water system leads to the formation of isomeric 1-benzoyl- and 2-benzoyl-5-aryltetrazoles.The ratio of the isomers depens on the nature of the substituents in the phenyl ring; electron-withdrawing substituents increase the proportion of the N2 isomer.The respective 2,5-disubstituted 1,3,4-oxadiazoles are formed during thermolysis, irrespective of the position of the benzoyl group in the N-benzoyltetrazoles.
