73229-28-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 73229-28-4 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 9 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 73229-28:
(7*7)+(6*3)+(5*2)+(4*2)+(3*9)+(2*2)+(1*8)=124
124 % 10 = 4
So 73229-28-4 is a valid CAS Registry Number.
