40889-43-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 40889-43-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,8,8 and 9 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 40889-43:
(7*4)+(6*0)+(5*8)+(4*8)+(3*9)+(2*4)+(1*3)=138
138 % 10 = 8
So 40889-43-8 is a valid CAS Registry Number.
