77431-73-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77431-73-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,4,3 and 1 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 77431-73:
(7*7)+(6*7)+(5*4)+(4*3)+(3*1)+(2*7)+(1*3)=143
143 % 10 = 3
So 77431-73-3 is a valid CAS Registry Number.
