64822-81-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 64822-81-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,8,2 and 2 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 64822-81:
(7*6)+(6*4)+(5*8)+(4*2)+(3*2)+(2*8)+(1*1)=137
137 % 10 = 7
So 64822-81-7 is a valid CAS Registry Number.

Unified synthesis of C1-C19 building blocks of halichondrins via selective activation/coupling of polyhalogenated nucleophiles in (Ni)/Cr-Mediated reactions

Li, Jingwei,Yan, Wuming,Kishi, Yoshito

, p. 6226 - 6231 (2015)

A unified synthesis of the C1-C19 building blocks 8-10 of halichondrins A-C was developed from the common synthetic intermediates 26a,b. Acetylenic ketones 26a,b were in turn synthesized via selective activation/coupling of polyhalogenated nucleophiles 23

CHROMIUM-MEDIATED COUPLING AND APPLICATION TO THE SYNTHESIS OF HALICHONDRINS

-

Paragraph 00453; 00455, (2016/11/17)

The present invention provides unified synthesis of the CI -CI 9 building blocks of halichondrins and analogs theoreof using selective coupling of poly-halogenated nucleophiles in chromium-mediated coupling reactions. The present invention also provides a practical and efficient synthesis of C20-C38 building blocks of halichondrins and analogs thereof. Also provided herein are general methods of selective activation and coupling of poly-halogenated analogs with an aldehyde. The provided coupling reactions are selective for halo-enone and halo-acetylenic ketal over vinyl halide and halide attached to a sp hydridized carbon. The provided efficient selective coupling reactions can allow easy access to the CI -CI 9 building blocks and C20-C38 building blocks of halichondrins and analogs thereof with limited or no purification or separation of the intermediates.
