81183-20-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 81183-20-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,1,8 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 81183-20:
(7*8)+(6*1)+(5*1)+(4*8)+(3*3)+(2*2)+(1*0)=112
112 % 10 = 2
So 81183-20-2 is a valid CAS Registry Number.
