39673-19-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 39673-19-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,6,7 and 3 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 39673-19:
(7*3)+(6*9)+(5*6)+(4*7)+(3*3)+(2*1)+(1*9)=153
153 % 10 = 3
So 39673-19-3 is a valid CAS Registry Number.
