Check Digit Verification of cas no
The CAS Registry Mumber 39981-04-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,9,8 and 1 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 39981-04:
(7*3)+(6*9)+(5*9)+(4*8)+(3*1)+(2*0)+(1*4)=159
159 % 10 = 9
So 39981-04-9 is a valid CAS Registry Number.
