Check Digit Verification of cas no

The CAS Registry Mumber 402913-52-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,2,9,1 and 3 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 402913-52:
(8*4)+(7*0)+(6*2)+(5*9)+(4*1)+(3*3)+(2*5)+(1*2)=114
114 % 10 = 4
So 402913-52-4 is a valid CAS Registry Number.

Enantioselective synthesis of β,β-dialkyl α-hydroxy γ-butyrolactones

Pansare, Sunil V.,Bhattacharyya, Annyt

, p. 9265 - 9267 (2001)

An ephedrine-derived morpholine dione is employed in the synthesis of chiral alkylidene morpholinones that are efficiently converted to β-substituted α,γ-dihydroxy butyramides, precursors of the corresponding butyrolactones. Enantioselective synthesis of a spiro analog of pantolactone as well as a naturally occurring pantolactone homolog is achieved with this protocol.

Enantioselective synthesis of pantolactone analogues from an ephedrine-derived morpholine-dione

Pansare, Sunil V.,Bhattacharyya, Annyt

, p. 3275 - 3282 (2007/10/03)

An efficient enantioselective synthesis of β,β-dialkyl α-hydroxy γ-butyrolactones, analogues of pantolactone, has been developed employing a stereoselective Prins reaction of chiral alkylidene morpholinones, as the key step. Enantioselective synthesis of a naturally occurring pantolactone homologue and a spiro analogue of pantolactone was achieved with this protocol.
