23230-02-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 23230-02-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,2,3 and 0 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 23230-02:
(7*2)+(6*3)+(5*2)+(4*3)+(3*0)+(2*0)+(1*2)=56
56 % 10 = 6
So 23230-02-6 is a valid CAS Registry Number.
