74172-76-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74172-76-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,1,7 and 2 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 74172-76:
(7*7)+(6*4)+(5*1)+(4*7)+(3*2)+(2*7)+(1*6)=132
132 % 10 = 2
So 74172-76-2 is a valid CAS Registry Number.
