73420-71-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 73420-71-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,4,2 and 0 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 73420-71:
(7*7)+(6*3)+(5*4)+(4*2)+(3*0)+(2*7)+(1*1)=110
110 % 10 = 0
So 73420-71-0 is a valid CAS Registry Number.
