Check Digit Verification of cas no
The CAS Registry Mumber 132-68-3 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 8 respectively.
Calculate Digit Verification of CAS Registry Number 132-68:
(5*1)+(4*3)+(3*2)+(2*6)+(1*8)=43
43 % 10 = 3
So 132-68-3 is a valid CAS Registry Number.
