Check Digit Verification of cas no

The CAS Registry Mumber 121163-64-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,1,6 and 3 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 121163-64:
(8*1)+(7*2)+(6*1)+(5*1)+(4*6)+(3*3)+(2*6)+(1*4)=82
82 % 10 = 2
So 121163-64-2 is a valid CAS Registry Number.

A Facile 1,3-Dipolar Cycloaddition of Nitrile Oxides to Chlorocarbonyl Isocyanate: Synthesis of 4-Chlorocarbonyl-5-oxo-4,5-dihydro-1,2,4-oxadiazoles

Rao, K. Rama,Nageswar, Y. V. D.,Gangadhar, A.,Sattur, P. B.

, p. 994 - 995 (1988)

The 1,3-dipolar cycloaddition of substituted benzonitrile oxides to the C=N group of chlorocarbonyl isocyanate in chloroform gives potentially useful 3-aryl-4-chlorocarbonyl-5-oxo-4,5-dihydro-1,2,4-oxadiazoles in 75-80percent yields.
