273223-61-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 273223-61-3 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, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 273223-61:
(8*2)+(7*7)+(6*3)+(5*2)+(4*2)+(3*3)+(2*6)+(1*1)=123
123 % 10 = 3
So 273223-61-3 is a valid CAS Registry Number.
