133859-59-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133859-59-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,8,5 and 9 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 133859-59:
(8*1)+(7*3)+(6*3)+(5*8)+(4*5)+(3*9)+(2*5)+(1*9)=153
153 % 10 = 3
So 133859-59-3 is a valid CAS Registry Number.

ASYMMETRIC SYNTHESIS OF D-erythro-SPHINGOSINE
Groth, Ulrich,Schoellkopf, Ulrich,Tiller, Thomas
, p. 2835 - 2842 (2007/10/02)
D-erythro-Sphingosine 9 is a building block of cerebrosides and glycosphingolipids and was synthesized in 5 steps via an asymmetric aldol addition of the lithiated bislactim ether of cyclo-(L-Val-Gly) 4 to (2E)-hexadecenal (3) in an overall yield of 21percent.
