Check Digit Verification of cas no
The CAS Registry Mumber 40133-12-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,1,3 and 3 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 40133-12:
(7*4)+(6*0)+(5*1)+(4*3)+(3*3)+(2*1)+(1*2)=58
58 % 10 = 8
So 40133-12-8 is a valid CAS Registry Number.
