Check Digit Verification of cas no
The CAS Registry Mumber 15790-15-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,7,9 and 0 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 15790-15:
(7*1)+(6*5)+(5*7)+(4*9)+(3*0)+(2*1)+(1*5)=115
115 % 10 = 5
So 15790-15-5 is a valid CAS Registry Number.
