Check Digit Verification of cas no

The CAS Registry Mumber 142285-65-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,2,8 and 5 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 142285-65:
(8*1)+(7*4)+(6*2)+(5*2)+(4*8)+(3*5)+(2*6)+(1*5)=122
122 % 10 = 2
So 142285-65-2 is a valid CAS Registry Number.

Synthesis of enantiopure bis-aziridines, bis-epoxides, and aziridino-epoxides from d-mannitol

Sureshkumar, Devarajulu,Maity, Susama,Chandrasekaran, Srinivasan

, p. 10162 - 10170 (2007/10/03)

A practical synthesis of enantiopure bis-aziridines 11 and 15, bis-epoxides 12 and 17, and aziridino-epoxides 27 and 30 is reported using inexpensive d-mannitol as the starting material. The key transformation involves the reductive cleavage of bis-benzyl

Synthesis of C2-symmetric guanidino-sugars as potent inhibitors of glycosidases

Le Merrer, Yves,Gauzy, Laurence,Gravier-Pelletier, Christine,Depezay, Jean-Claude

, p. 307 - 320 (2007/10/03)

A series of enantiomerically pure C2-Symmetric guanidino-sugars was synthesized from D-mannitol. The first method described involves direct opening of a bis-epoxide by guanidine, whereas the second one deals with a mercury-catalyzed transformation of a cyclic thiourea into a N,N',N'- trisubstituted guanidine as a key step. The biological activity of these compounds towards several glycosidases has been evaluated. One of them (5) was found to selectively inhibit α-L-fucosidase of bovin kidney (2.8 μM).
