4Check Digit Verification of cas no
The CAS Registry Mumber 3687-83-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,6,8 and 7 respectively; the second part has 2 digits, 8 and 3 respectively.Calculate Digit Verification of CAS Registry Number 3687-83:
(6*3)+(5*6)+(4*8)+(3*7)+(2*8)+(1*3)=120
120 % 10 = 0
So 3687-83-0 is a valid CAS Registry Number.
