74974-72-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74974-72-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,9,7 and 4 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 74974-72:
(7*7)+(6*4)+(5*9)+(4*7)+(3*4)+(2*7)+(1*2)=174
174 % 10 = 4
So 74974-72-4 is a valid CAS Registry Number.
