Check Digit Verification of cas no
The CAS Registry Mumber 133940-72-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,9,4 and 0 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 133940-72:
(8*1)+(7*3)+(6*3)+(5*9)+(4*4)+(3*0)+(2*7)+(1*2)=124
124 % 10 = 4
So 133940-72-4 is a valid CAS Registry Number.
