Check Digit Verification of cas no
The CAS Registry Mumber 132-62-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,3 and 2 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 132-62:
(5*1)+(4*3)+(3*2)+(2*6)+(1*2)=37
37 % 10 = 7
