Check Digit Verification of cas no
The CAS Registry Mumber 133639-32-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,6,3 and 9 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 133639-32:
(8*1)+(7*3)+(6*3)+(5*6)+(4*3)+(3*9)+(2*3)+(1*2)=124
124 % 10 = 4
So 133639-32-4 is a valid CAS Registry Number.
