73221-39-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 73221-39-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,2,2 and 1 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 73221-39:
(7*7)+(6*3)+(5*2)+(4*2)+(3*1)+(2*3)+(1*9)=103
103 % 10 = 3
So 73221-39-3 is a valid CAS Registry Number.
