Check Digit Verification of cas no
The CAS Registry Mumber 39503-41-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,5,0 and 3 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 39503-41:
(7*3)+(6*9)+(5*5)+(4*0)+(3*3)+(2*4)+(1*1)=118
118 % 10 = 8
So 39503-41-8 is a valid CAS Registry Number.
