172546-93-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 172546-93-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,2,5,4 and 6 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 172546-93:
(8*1)+(7*7)+(6*2)+(5*5)+(4*4)+(3*6)+(2*9)+(1*3)=149
149 % 10 = 9
So 172546-93-9 is a valid CAS Registry Number.
