138395-78-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 138395-78-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,3,9 and 5 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 138395-78:
(8*1)+(7*3)+(6*8)+(5*3)+(4*9)+(3*5)+(2*7)+(1*8)=165
165 % 10 = 5
So 138395-78-5 is a valid CAS Registry Number.

Asymmetric desymmetrization of meso-cyclopentitol using a C2-symmetric bis-sulfoxide: A synthesis of (-)-allosamizoline

Maezaki, Naoyoshi,Sakamoto, Atsunobu,Tanaka, Tetsuaki,Iwata, Chuzo

, p. 179 - 182 (2007/10/03)

A synthesis of (-)-allosamizoline was accomplished via asymmetric desymmetrization of a meso-cyclopentitol using the C2-symmetric bis-sulfoxide 5 as a chiral auxiliary.

Enantiospecific total synthesis of (-)-allosamizoline, and aminocyclitol moiety of the insect chitinase inhibitor allosamidin

Nakata, Masaya,Akazawa, Seiji,Kitamura, Shuji,Tatsuta, Kuniaki

, p. 5363 - 5366 (2007/10/02)

Total synthesis of (-)-allosamizoline (2), an aminocyclitol moiety of the insect chitinase inhibitor allosamidin (1) has been enantiospecifically synthesized from D-glucosamine by using an intramolecular cycloaddition of the nitrile oxide to an olefin as a key step.
