76173-72-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 76173-72-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,1,7 and 3 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 76173-72:
(7*7)+(6*6)+(5*1)+(4*7)+(3*3)+(2*7)+(1*2)=143
143 % 10 = 3
So 76173-72-3 is a valid CAS Registry Number.
