Check Digit Verification of cas no
The CAS Registry Mumber 108871-73-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,8,7 and 1 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 108871-73:
(8*1)+(7*0)+(6*8)+(5*8)+(4*7)+(3*1)+(2*7)+(1*3)=144
144 % 10 = 4
So 108871-73-4 is a valid CAS Registry Number.
