Check Digit Verification of cas no
The CAS Registry Mumber 13463-42-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,4,6 and 3 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 13463-42:
(7*1)+(6*3)+(5*4)+(4*6)+(3*3)+(2*4)+(1*2)=88
88 % 10 = 8
So 13463-42-8 is a valid CAS Registry Number.
