204976-83-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 204976-83-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,4,9,7 and 6 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 204976-83:
(8*2)+(7*0)+(6*4)+(5*9)+(4*7)+(3*6)+(2*8)+(1*3)=150
150 % 10 = 0
So 204976-83-0 is a valid CAS Registry Number.
