Check Digit Verification of cas no
The CAS Registry Mumber 133383-83-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,3,8 and 3 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 133383-83:
(8*1)+(7*3)+(6*3)+(5*3)+(4*8)+(3*3)+(2*8)+(1*3)=122
122 % 10 = 2
So 133383-83-2 is a valid CAS Registry Number.
