Check Digit Verification of cas no
The CAS Registry Mumber 111180-72-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,1,8 and 0 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 111180-72:
(8*1)+(7*1)+(6*1)+(5*1)+(4*8)+(3*0)+(2*7)+(1*2)=74
74 % 10 = 4
So 111180-72-4 is a valid CAS Registry Number.
