74731-72-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74731-72-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,7,3 and 1 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 74731-72:
(7*7)+(6*4)+(5*7)+(4*3)+(3*1)+(2*7)+(1*2)=139
139 % 10 = 9
So 74731-72-9 is a valid CAS Registry Number.
