Check Digit Verification of cas no

The CAS Registry Mumber 90160-97-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,1,6 and 0 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 90160-97:
(7*9)+(6*0)+(5*1)+(4*6)+(3*0)+(2*9)+(1*7)=117
117 % 10 = 7
So 90160-97-7 is a valid CAS Registry Number.

A NEW OXIGENATING METHOD USING 1-ALKOXYCARBONYL-1,2,4-TRIAZOLES AND HYDROGEN PEROXIDE RELATIVE REACTIVITY OF O-ALKYLPEROXYCARBONIC ACIDS

Tsunokawa, Youko,Iwasaki, Shigeo,Okuda, Shigenobu

, p. 4578 - 4581 (2007/10/02)

A convenient method is reported for the epoxidation of alkenes and the Baeyer-Villiger oxidation of a variety of carbonyl compounds using the 1-alkoxycarbonyl-1,2,4-triazoles (1a-c)/H2O2 system.The reactivities of the resulting peroxycarbonic acids were compared.O-Trichloroethylperoxycarbonic acid prepared in this way was isolated as a chloroform solution and was characterized spectroscopically.KEYWORDS - oxygenation with 1-alkoxycarbonyl-1,2,4-triazole/H2O2 system; peroxycarbonic acid; epoxidation; Baeyer-Villiger reaction
