42510-46-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 42510-46-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,5,1 and 0 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 42510-46:
(7*4)+(6*2)+(5*5)+(4*1)+(3*0)+(2*4)+(1*6)=83
83 % 10 = 3
So 42510-46-3 is a valid CAS Registry Number.
