443791-89-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 443791-89-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,3,7,9 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 443791-89:
(8*4)+(7*4)+(6*3)+(5*7)+(4*9)+(3*1)+(2*8)+(1*9)=177
177 % 10 = 7
So 443791-89-7 is a valid CAS Registry Number.
