Check Digit Verification of cas no
The CAS Registry Mumber 80780-15-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,7,8 and 0 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 80780-15:
(7*8)+(6*0)+(5*7)+(4*8)+(3*0)+(2*1)+(1*5)=130
130 % 10 = 0
So 80780-15-0 is a valid CAS Registry Number.
