23623-26-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 23623-26-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,6,2 and 3 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 23623-26:
(7*2)+(6*3)+(5*6)+(4*2)+(3*3)+(2*2)+(1*6)=89
89 % 10 = 9
So 23623-26-9 is a valid CAS Registry Number.
