444995-73-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 444995-73-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,4,9,9 and 5 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 444995-73:
(8*4)+(7*4)+(6*4)+(5*9)+(4*9)+(3*5)+(2*7)+(1*3)=197
197 % 10 = 7
So 444995-73-7 is a valid CAS Registry Number.
