73230-82-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 73230-82-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,2,3 and 0 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 73230-82:
(7*7)+(6*3)+(5*2)+(4*3)+(3*0)+(2*8)+(1*2)=107
107 % 10 = 7
So 73230-82-7 is a valid CAS Registry Number.
