Check Digit Verification of cas no
The CAS Registry Mumber 6632-12-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,3 and 2 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 6632-12:
(6*6)+(5*6)+(4*3)+(3*2)+(2*1)+(1*2)=88
88 % 10 = 8
So 6632-12-8 is a valid CAS Registry Number.
