Check Digit Verification of cas no
The CAS Registry Mumber 209328-72-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,9,3,2 and 8 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 209328-72:
(8*2)+(7*0)+(6*9)+(5*3)+(4*2)+(3*8)+(2*7)+(1*2)=133
133 % 10 = 3
So 209328-72-3 is a valid CAS Registry Number.
