Check Digit Verification of cas no
The CAS Registry Mumber 33300-19-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,3,0 and 0 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 33300-19:
(7*3)+(6*3)+(5*3)+(4*0)+(3*0)+(2*1)+(1*9)=65
65 % 10 = 5
So 33300-19-5 is a valid CAS Registry Number.
