Check Digit Verification of cas no
The CAS Registry Mumber 82-29-1 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 2 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 82-29:
(4*8)+(3*2)+(2*2)+(1*9)=51
51 % 10 = 1
So 82-29-1 is a valid CAS Registry Number.
