71208-83-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 71208-83-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,2,0 and 8 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 71208-83:
(7*7)+(6*1)+(5*2)+(4*0)+(3*8)+(2*8)+(1*3)=108
108 % 10 = 8
So 71208-83-8 is a valid CAS Registry Number.
