73275-75-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 73275-75-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,2,7 and 5 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 73275-75:
(7*7)+(6*3)+(5*2)+(4*7)+(3*5)+(2*7)+(1*5)=139
139 % 10 = 9
So 73275-75-9 is a valid CAS Registry Number.
