175165-67-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 175165-67-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,5,1,6 and 5 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 175165-67:
(8*1)+(7*7)+(6*5)+(5*1)+(4*6)+(3*5)+(2*6)+(1*7)=150
150 % 10 = 0
So 175165-67-0 is a valid CAS Registry Number.
