Check Digit Verification of cas no
The CAS Registry Mumber 39665-89-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,6,6 and 5 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 39665-89:
(7*3)+(6*9)+(5*6)+(4*6)+(3*5)+(2*8)+(1*9)=169
169 % 10 = 9
So 39665-89-9 is a valid CAS Registry Number.
