Check Digit Verification of cas no
The CAS Registry Mumber 133333-30-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,3,3 and 3 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 133333-30:
(8*1)+(7*3)+(6*3)+(5*3)+(4*3)+(3*3)+(2*3)+(1*0)=89
89 % 10 = 9
So 133333-30-9 is a valid CAS Registry Number.
