261165-17-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 261165-17-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,1,1,6 and 5 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 261165-17:
(8*2)+(7*6)+(6*1)+(5*1)+(4*6)+(3*5)+(2*1)+(1*7)=117
117 % 10 = 7
So 261165-17-7 is a valid CAS Registry Number.
