91669-17-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91669-17-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,6,6 and 9 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 91669-17:
(7*9)+(6*1)+(5*6)+(4*6)+(3*9)+(2*1)+(1*7)=159
159 % 10 = 9
So 91669-17-9 is a valid CAS Registry Number.
