89711-23-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89711-23-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,7,1 and 1 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 89711-23:
(7*8)+(6*9)+(5*7)+(4*1)+(3*1)+(2*2)+(1*3)=159
159 % 10 = 9
So 89711-23-9 is a valid CAS Registry Number.
