32973-76-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 32973-76-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,2,9,7 and 3 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 32973-76:
(7*3)+(6*2)+(5*9)+(4*7)+(3*3)+(2*7)+(1*6)=135
135 % 10 = 5
So 32973-76-5 is a valid CAS Registry Number.
