273223-59-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 273223-59-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,7,3,2,2 and 3 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 273223-59:
(8*2)+(7*7)+(6*3)+(5*2)+(4*2)+(3*3)+(2*5)+(1*9)=129
129 % 10 = 9
So 273223-59-9 is a valid CAS Registry Number.
