90108-54-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90108-54-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,1,0 and 8 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 90108-54:
(7*9)+(6*0)+(5*1)+(4*0)+(3*8)+(2*5)+(1*4)=106
106 % 10 = 6
So 90108-54-6 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.
