General Description

(+)-Dehydroabietic acid is a naturally occurring diterpene resin acid that is found in various coniferous tree species. It is a primary constituent of rosin, a natural resin commonly used in adhesives, solvents, and inks. (+)-Dehydroabietic acid has been studied for its potential anti-inflammatory, antioxidant, and antimicrobial properties. It has also shown promise as a compound for use in pharmaceuticals and cosmetics. Additionally, research suggests that (+)-Dehydroabietic acid may have potential applications in the agriculture industry for its ability to enhance plant growth and protect against pathogens. Overall, the compound has garnered significant interest for its diverse range of potential industrial and medicinal uses.

Check Digit Verification of cas no

The CAS Registry Mumber 1231-75-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,3 and 1 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1231-75:
(6*1)+(5*2)+(4*3)+(3*1)+(2*7)+(1*5)=50
50 % 10 = 0
So 1231-75-0 is a valid CAS Registry Number.

Oxonitriles: Multicomponent Grignard addition-alkylations

Fleming, Fraser F.,Zhang, Zhiyu,Wang, Qunzhao,Steward, Omar W.

, p. 1126 - 1129 (2007/10/03)

Three at a time: Sequential carbonyl addition, chelation-controlled conjugate addition, and alkylation triggers the multicomponent assembly of diverse nitriles. The chelation-controlled conjugate addition-alkylation installs three new stereocenters (see scheme), thereby generating substituted nitriles that are ideal terpenoid precursors as illustrated in the synthesis of epi-dehydroabietic acid.
