Check Digit Verification of cas no
The CAS Registry Mumber 91821-95-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,8,2 and 1 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 91821-95:
(7*9)+(6*1)+(5*8)+(4*2)+(3*1)+(2*9)+(1*5)=143
143 % 10 = 3
So 91821-95-3 is a valid CAS Registry Number.
