Check Digit Verification of cas no
The CAS Registry Mumber 132640-96-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,6,4 and 0 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 132640-96:
(8*1)+(7*3)+(6*2)+(5*6)+(4*4)+(3*0)+(2*9)+(1*6)=111
111 % 10 = 1
So 132640-96-1 is a valid CAS Registry Number.
