Check Digit Verification of cas no
The CAS Registry Mumber 13656-50-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,6,5 and 6 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 13656-50:
(7*1)+(6*3)+(5*6)+(4*5)+(3*6)+(2*5)+(1*0)=103
103 % 10 = 3
So 13656-50-3 is a valid CAS Registry Number.
