284028-80-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 284028-80-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,4,0,2 and 8 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 284028-80:
(8*2)+(7*8)+(6*4)+(5*0)+(4*2)+(3*8)+(2*8)+(1*0)=144
144 % 10 = 4
So 284028-80-4 is a valid CAS Registry Number.

Efficient enantioselective syntheses of chloramphenicol and (D)-threo- and (D)-erythro-sphingosine
Corey,Choi, Soongyu
, p. 2765 - 2768 (2007/10/03)
The chiral diazaborolidine 1 has been applied to the enantioselective syntheses of chloramphenicol (2) and (D)-threo-N-acetylsphingosine (3), a synthetic precursor of the diastereomeric (D)-sphingosines. (C) 2000 Elsevier Science Ltd.
