172754-37-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 172754-37-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,2,7,5 and 4 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 172754-37:
(8*1)+(7*7)+(6*2)+(5*7)+(4*5)+(3*4)+(2*3)+(1*7)=149
149 % 10 = 9
So 172754-37-9 is a valid CAS Registry Number.
