Check Digit Verification of cas no

The CAS Registry Mumber 93213-90-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,2,1 and 3 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 93213-90:
(7*9)+(6*3)+(5*2)+(4*1)+(3*3)+(2*9)+(1*0)=122
122 % 10 = 2
So 93213-90-2 is a valid CAS Registry Number.

Studies in Spiroheterocycles. Part V. Synthesis of New Fluorinated Spiro-2(1H)-ones

Joshi, Krishna C.,Jain, Renuka,Garg, Saroj

, p. 977 - 979 (2007/10/02)

Reinvestigation of the reaction of 3-aroylmethyleneindol-2-ones with hydrogen peroxide has revealed that a 1:1 isomeric mixture of spiro-2(1H)-ones is formed.The structure of the two isomers have been confirmed by their ir, pmr and mass spectral studies.Mass fragmentation patterns of these compounds are discussed.
