Check Digit Verification of cas no
The CAS Registry Mumber 139-45-7 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 9 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 139-45:
(5*1)+(4*3)+(3*9)+(2*4)+(1*5)=57
57 % 10 = 7
So 139-45-7 is a valid CAS Registry Number.
