81028-13-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 81028-13-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,0,2 and 8 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 81028-13:
(7*8)+(6*1)+(5*0)+(4*2)+(3*8)+(2*1)+(1*3)=99
99 % 10 = 9
So 81028-13-9 is a valid CAS Registry Number.

A convergent and stereoselective total synthesis of phomolides G and H

Subba Reddy,Sivaramakrishna Reddy,Phaneendra Reddy,Yadav

, p. 501 - 504 (2014/03/21)

A stereoselective total synthesis of phomolides G and H, a polyketide natural products is described. The synthesis involves organocatalytic enantioselective asymmetric epoxidation, C1-Wittig olefination, and ring-closing metathesis as key steps. The use of organocatalytic MacMillan asymmetric epoxidation for the construction of two chiral centers of phomolides G and H makes this approach more attractive.

A New Method for the Dehydration of β-Hydroxy Sulfones: Synthesis of (E,S)-γ-Hydroxy-α,β-unsaturated Sulfones and (S)-ε-Hydroxy-(E,E)-α,γ-dienyl Sulfones

Kang, Suk-Ku,Park, Young-Won,Kim, Sung-Gyu,Jeon, Jae-Hoon

, p. 405 - 406 (2007/10/02)

Optically active (E,S)-γ-hydroxy-α,β-unsaturated sulfones and (S)-ε-hydroxy-(E,E)-α,γ-dienyl sulfones have been prepared in a one-pot dehydration procedure from β,γ-dihydroxy sulfones and δ,ε-dihydroxy allyl sulfones, respectively, via an elimination reac
