Check Digit Verification of cas no
The CAS Registry Mumber 128652-20-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,6,5 and 2 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 128652-20:
(8*1)+(7*2)+(6*8)+(5*6)+(4*5)+(3*2)+(2*2)+(1*0)=130
130 % 10 = 0
So 128652-20-0 is a valid CAS Registry Number.
