232945-34-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 232945-34-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,3,2,9,4 and 5 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 232945-34:
(8*2)+(7*3)+(6*2)+(5*9)+(4*4)+(3*5)+(2*3)+(1*4)=135
135 % 10 = 5
So 232945-34-5 is a valid CAS Registry Number.
