Check Digit Verification of cas no
The CAS Registry Mumber 204120-73-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,4,1,2 and 0 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 204120-73:
(8*2)+(7*0)+(6*4)+(5*1)+(4*2)+(3*0)+(2*7)+(1*3)=70
70 % 10 = 0
So 204120-73-0 is a valid CAS Registry Number.
