62403-73-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 62403-73-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,2,4,0 and 3 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 62403-73:
(7*6)+(6*2)+(5*4)+(4*0)+(3*3)+(2*7)+(1*3)=100
100 % 10 = 0
So 62403-73-0 is a valid CAS Registry Number.
