Check Digit Verification of cas no
The CAS Registry Mumber 26833-85-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,8,3 and 3 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 26833-85:
(7*2)+(6*6)+(5*8)+(4*3)+(3*3)+(2*8)+(1*5)=132
132 % 10 = 2
So 26833-85-2 is a valid CAS Registry Number.

Synthesis method and intermediate of ester derivative of (-)-cephalotaxine
-
Paragraph 0213-0215, (2019/12/29)
The invention discloses a synthesis method and an intermediate of an ester derivative of (-)-cephalotaxine. The synthesis method is characterized in that a compound A and a compound 4 undergoes a condensation reaction shown in the description in a solvent under the action of a condensing agent in order to obtain a compound I. The synthetic method utilizes an esterification reaction of a racemic epoxy branched-chain compound and the (-)-cephalotaxine to highly selectively obtain the chiral compound close to a single configuration, so the method has the advantages of simple and mild synthesis route, and easiness in industrialization.

We report a protocol for efficient stereoselective installation of the chiral oxygen-containing tetrasubstituted tertiary carbon stereocenter of the side chain of cephalotaxus esters by means of highly diastereoselective Mukaiyama aldol reactions between α-keto esters (2) and a (Z)-α-chloro ketene silyl acetal. This protocol permitted synthesis of cephalotaxus esters including six natural products in good to excellent yields (up to 94%) with high diastereoselectivities (dr up to 97:3) and could be performed on a multigram scale.
