23004-96-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 23004-96-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,0,0 and 4 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 23004-96:
(7*2)+(6*3)+(5*0)+(4*0)+(3*4)+(2*9)+(1*6)=68
68 % 10 = 8
So 23004-96-8 is a valid CAS Registry Number.
