172754-49-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 172754-49-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,2,7,5 and 4 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 172754-49:
(8*1)+(7*7)+(6*2)+(5*7)+(4*5)+(3*4)+(2*4)+(1*9)=153
153 % 10 = 3
So 172754-49-3 is a valid CAS Registry Number.
