Check Digit Verification of cas no
The CAS Registry Mumber 3180-81-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,1,8 and 0 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 3180-81:
(6*3)+(5*1)+(4*8)+(3*0)+(2*8)+(1*1)=72
72 % 10 = 2
So 3180-81-2 is a valid CAS Registry Number.
