Check Digit Verification of cas no
The CAS Registry Mumber 198632-95-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,8,6,3 and 2 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 198632-95:
(8*1)+(7*9)+(6*8)+(5*6)+(4*3)+(3*2)+(2*9)+(1*5)=190
190 % 10 = 0
So 198632-95-0 is a valid CAS Registry Number.
