Check Digit Verification of cas no
The CAS Registry Mumber 65865-08-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,8,6 and 5 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 65865-08:
(7*6)+(6*5)+(5*8)+(4*6)+(3*5)+(2*0)+(1*8)=159
159 % 10 = 9
So 65865-08-9 is a valid CAS Registry Number.
