Check Digit Verification of cas no
The CAS Registry Mumber 165260-55-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,5,2,6 and 0 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 165260-55:
(8*1)+(7*6)+(6*5)+(5*2)+(4*6)+(3*0)+(2*5)+(1*5)=129
129 % 10 = 9
So 165260-55-9 is a valid CAS Registry Number.
