238757-51-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 238757-51-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,3,8,7,5 and 7 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 238757-51:
(8*2)+(7*3)+(6*8)+(5*7)+(4*5)+(3*7)+(2*5)+(1*1)=172
172 % 10 = 2
So 238757-51-2 is a valid CAS Registry Number.

Studies towards the total synthesis of (-)-callystatin A

Yadav,Yadagiri,Madhuri, Ch.,Sabitha

scheme or table, p. 4269 - 4272 (2011/09/12)

The synthesis of C1-C12 and C13-C 22 fragments of (-)-callystatin A is accomplished employing desymmetrization strategy for the creation of five chiral centres of the polypropionate fragment and application of c

Formal total synthesis of (-)-saliniketals

Yadav,Hossain, Sk. Samad,Madhu, Madasu,Mohapatra, Debendra K.

supporting information; experimental part, p. 8822 - 8825 (2010/03/01)

(Chemical Equation Presented) A highly stereoselective formal total synthesis of the ornithine decarboxylase inhibitors (-)-saliniketals A and B is described. The salient features of the synthesis are the utilization of a desymmetrization technique to cre

An efficient synthesis of (+)-prelactone B

Yadav,Reddy, K. Bhaskar,Sabitha

, p. 6475 - 6476 (2007/10/03)

An enantioselective synthesis of (+)-prelactone B 1 has been achieved on a multigram scale starting from a known bicyclic precursor 2. The key feature of the strategy is the generation of 3-stereogenic centres from a single bicyclic precursor, which has b
