32234-66-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 32234-66-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,2,2,3 and 4 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 32234-66:
(7*3)+(6*2)+(5*2)+(4*3)+(3*4)+(2*6)+(1*6)=85
85 % 10 = 5
So 32234-66-5 is a valid CAS Registry Number.
