Check Digit Verification of cas no
The CAS Registry Mumber 156-25-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,5 and 6 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 156-25:
(5*1)+(4*5)+(3*6)+(2*2)+(1*5)=52
52 % 10 = 2
So 156-25-2 is a valid CAS Registry Number.
