89448-50-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89448-50-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,4,4 and 8 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 89448-50:
(7*8)+(6*9)+(5*4)+(4*4)+(3*8)+(2*5)+(1*0)=180
180 % 10 = 0
So 89448-50-0 is a valid CAS Registry Number.

Use of D-Ribonolactone in Organic Synthesis. 2. Scope and Utility
Chen, Shin-Yih,Joullie, Madeleine M.
, p. 2168 - 2174 (2007/10/02)
The scope and utility of D-ribonolactone (1) as chiral template for the synthesis of optically active γ-lactones which are important precursors for many natural products are discussed.The regio- and stereoselective functionalization of 1 is examined.
