461-42-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 461-42-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,6 and 1 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 461-42:
(5*4)+(4*6)+(3*1)+(2*4)+(1*2)=57
57 % 10 = 7
So 461-42-7 is a valid CAS Registry Number.
