111669-65-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 111669-65-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,6,6 and 9 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 111669-65:
(8*1)+(7*1)+(6*1)+(5*6)+(4*6)+(3*9)+(2*6)+(1*5)=119
119 % 10 = 9
So 111669-65-9 is a valid CAS Registry Number.
