Check Digit Verification of cas no
The CAS Registry Mumber 135-55-7 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 5 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 135-55:
(5*1)+(4*3)+(3*5)+(2*5)+(1*5)=47
47 % 10 = 7
So 135-55-7 is a valid CAS Registry Number.
