74115-72-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74115-72-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,1,1 and 5 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 74115-72:
(7*7)+(6*4)+(5*1)+(4*1)+(3*5)+(2*7)+(1*2)=113
113 % 10 = 3
So 74115-72-3 is a valid CAS Registry Number.
