83004-73-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 83004-73-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,0,0 and 4 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 83004-73:
(7*8)+(6*3)+(5*0)+(4*0)+(3*4)+(2*7)+(1*3)=103
103 % 10 = 3
So 83004-73-3 is a valid CAS Registry Number.
