49578-45-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 49578-45-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,9,5,7 and 8 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 49578-45:
(7*4)+(6*9)+(5*5)+(4*7)+(3*8)+(2*4)+(1*5)=172
172 % 10 = 2
So 49578-45-2 is a valid CAS Registry Number.
