41721-20-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 41721-20-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,7,2 and 1 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 41721-20:
(7*4)+(6*1)+(5*7)+(4*2)+(3*1)+(2*2)+(1*0)=84
84 % 10 = 4
So 41721-20-4 is a valid CAS Registry Number.
