38865-43-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 38865-43-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,8,6 and 5 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 38865-43:
(7*3)+(6*8)+(5*8)+(4*6)+(3*5)+(2*4)+(1*3)=159
159 % 10 = 9
So 38865-43-9 is a valid CAS Registry Number.
