173040-53-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 173040-53-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,3,0,4 and 0 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 173040-53:
(8*1)+(7*7)+(6*3)+(5*0)+(4*4)+(3*0)+(2*5)+(1*3)=104
104 % 10 = 4
So 173040-53-4 is a valid CAS Registry Number.
