245047-73-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 245047-73-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,5,0,4 and 7 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 245047-73:
(8*2)+(7*4)+(6*5)+(5*0)+(4*4)+(3*7)+(2*7)+(1*3)=128
128 % 10 = 8
So 245047-73-8 is a valid CAS Registry Number.
