32368-45-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 32368-45-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,2,3,6 and 8 respectively; the second part has 2 digits, 4 and 5 respectively.Calculate Digit Verification of CAS Registry Number 32368-45:
(7*3)+(6*2)+(5*3)+(4*6)+(3*8)+(2*4)+(1*5)=109
109 % 10 = 9
So 32368-45-9 is a valid CAS Registry Number.
