106928-26-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 106928-26-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,6,9,2 and 8 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 106928-26:
(8*1)+(7*0)+(6*6)+(5*9)+(4*2)+(3*8)+(2*2)+(1*6)=131
131 % 10 = 1
So 106928-26-1 is a valid CAS Registry Number.

Stereodivergent Total Synthesis of Hapalindoles, Fischerindoles, Hapalonamide H, and Ambiguine H Alkaloids by Developing a Biomimetic, Redox-Neutral, Cascade Prins-Type Cyclization

Sahu, Samrat,Das, Beauty,Maji, Modhu Sudan

, p. 6485 - 6489 (2018)

A stereoselective, redox-neutral, Br?nsted acid-catalyzed cascade Prins-type cyclization between indole and aldehyde is described to access several structurally diverse indole terpenoid scaffolds in a single step. Applying this concept, stereodivergent to

Total synthesis of hapalindoles J and U

Rafferty, Ryan J.,Williams, Robert M.

experimental part, p. 519 - 524 (2012/03/26)

The total synthesis of d,l-hapalindoles J and U has been accomplished. Hapalindole J was prepared in 11% overall yield over 11 synthetic steps and hapalindole U was prepared in 25% overall yield over 13 synthetic steps from commercially available materials. The route employs a novel silyl ether-based strategy for accessing the 6:5:6:6 ring system of the hapalindoles rapidly and in good yields.
