113278-73-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 113278-73-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,2,7 and 8 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 113278-73:
(8*1)+(7*1)+(6*3)+(5*2)+(4*7)+(3*8)+(2*7)+(1*3)=112
112 % 10 = 2
So 113278-73-2 is a valid CAS Registry Number.
