Check Digit Verification of cas no
The CAS Registry Mumber 3963-80-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,6 and 3 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 3963-80:
(6*3)+(5*9)+(4*6)+(3*3)+(2*8)+(1*0)=112
112 % 10 = 2
So 3963-80-2 is a valid CAS Registry Number.
