173550-17-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 173550-17-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,3,5,5 and 0 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 173550-17:
(8*1)+(7*7)+(6*3)+(5*5)+(4*5)+(3*0)+(2*1)+(1*7)=129
129 % 10 = 9
So 173550-17-9 is a valid CAS Registry Number.
