25874-16-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 25874-16-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,8,7 and 4 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 25874-16:
(7*2)+(6*5)+(5*8)+(4*7)+(3*4)+(2*1)+(1*6)=132
132 % 10 = 2
So 25874-16-2 is a valid CAS Registry Number.

A mild and environmentally benign method for the synthesis of glycals in PEG-600/H2O

Zhao, Jinzhong,Wei, Shanqiao,Ma, Xiaofeng,Shao, Huawu

, p. 1124 - 1127 (2009)

Glycals were synthesized via a simple, mild, convenient and environmentally benign procedure, in which protected glycosyl bromides undergo the reductive elimination in the presence of zinc in PEG-600/H2O at room temperature. The glycals were obtained in 75-92% isolated yields.

Total synthesis of (+)-cacospongionolide B

Oshida, Motoko,Ono, Misaki,Nakazaki, Atsuo,Kobayashi, Susumu

experimental part, p. 313 - 328 (2010/06/13)

Total synthesis of (+)-cacospongionolide B was achieved. The synthesis involved highly stereoselective C-glycosidation of a glycal derived from D-arabinose with 3-furyl boronic acid in the presence of a palladium catalyst and S-alkyl Suzuki-Miyaura coupling of in situ generated alkylborane prepared by the reaction of vinyl trans-decaMn with alkenyl triflate.
