1263941-46-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1263941-46-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,3,9,4 and 1 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1263941-46:
(9*1)+(8*2)+(7*6)+(6*3)+(5*9)+(4*4)+(3*1)+(2*4)+(1*6)=163
163 % 10 = 3
So 1263941-46-3 is a valid CAS Registry Number.

Synthesis of epothilones molecule fragment (15R)-C13-C 21 from D-mannitol
Kovalenko,Sokolov,Kulinkovich
experimental part, p. 1702 - 1708 (2011/03/18)
Efficient synthesis of an epothilone molecules fragment (15R)-C 13-C21 was carried out from D-mannitol through its conversion into methyl 2,3-O-cyclohexylidene-D-glycerate followed by the cyclopropanation of the ester group with ethy
