Check Digit Verification of cas no
The CAS Registry Mumber 39098-85-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,0,9 and 8 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 39098-85:
(7*3)+(6*9)+(5*0)+(4*9)+(3*8)+(2*8)+(1*5)=156
156 % 10 = 6
So 39098-85-6 is a valid CAS Registry Number.
