73093-19-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 73093-19-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,0,9 and 3 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 73093-19:
(7*7)+(6*3)+(5*0)+(4*9)+(3*3)+(2*1)+(1*9)=123
123 % 10 = 3
So 73093-19-3 is a valid CAS Registry Number.
