Check Digit Verification of cas no

The CAS Registry Mumber 129986-20-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,9,8 and 6 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 129986-20:
(8*1)+(7*2)+(6*9)+(5*9)+(4*8)+(3*6)+(2*2)+(1*0)=175
175 % 10 = 5
So 129986-20-5 is a valid CAS Registry Number.

Enantioselective synthesis of δ-/γ-alkoxy-β-hydroxy- α-alkyl-substituted Weinreb amides via DKR-ATH: Application to the synthesis of advanced intermediate of (-)-brevisamide

Kumaraswamy, Gullapalli,Narayana Murthy, Akula,Narayanarao, Vykunthapu,Vemulapalli, Sahithya Phani Babu,Bharatam, Jagadeesh

, p. 6751 - 6765 (2013/10/01)

A method of preparing stereodefined δ-/γ-alkoxy-β-hydroxy- α-alkyl-substituted Weinreb amides containing two successive hydroxyl-alkyl stereocenters has been developed. Further, this strategy coupled with organo-catalyzed asymmetric epoxidation culminates in the synthesis of a critical intermediate of (-)-brevisamide and its diastereomers.

Stereocontrolled total synthesis of (-)-ebelactone A.

Mandal, Amit K

, p. 2043 - 2045 (2007/10/03)

[structure: see text] The highly stereocontrolled hydroboration of an alkene, a subsequent Suzuki-Miyaura cross-coupling reaction, a silylcupration on a nonterminal acetylene, and an iododesilylation were the key steps in a convergent total synthesis of (
