Check Digit Verification of cas no
The CAS Registry Mumber 1132-05-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,3 and 2 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1132-05:
(6*1)+(5*1)+(4*3)+(3*2)+(2*0)+(1*5)=34
34 % 10 = 4
So 1132-05-4 is a valid CAS Registry Number.
