Check Digit Verification of cas no
The CAS Registry Mumber 1181-32-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,8 and 1 respectively; the second part has 2 digits, 3 and 2 respectively.Calculate Digit Verification of CAS Registry Number 1181-32:
(6*1)+(5*1)+(4*8)+(3*1)+(2*3)+(1*2)=54
54 % 10 = 4
So 1181-32-4 is a valid CAS Registry Number.
