129743-73-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129743-73-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,7,4 and 3 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 129743-73:
(8*1)+(7*2)+(6*9)+(5*7)+(4*4)+(3*3)+(2*7)+(1*3)=153
153 % 10 = 3
So 129743-73-3 is a valid CAS Registry Number.
