73414-40-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 73414-40-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,4,1 and 4 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 73414-40:
(7*7)+(6*3)+(5*4)+(4*1)+(3*4)+(2*4)+(1*0)=111
111 % 10 = 1
So 73414-40-1 is a valid CAS Registry Number.
