Check Digit Verification of cas no
The CAS Registry Mumber 111721-74-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,7,2 and 1 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 111721-74:
(8*1)+(7*1)+(6*1)+(5*7)+(4*2)+(3*1)+(2*7)+(1*4)=85
85 % 10 = 5
So 111721-74-5 is a valid CAS Registry Number.
