Check Digit Verification of cas no

The CAS Registry Mumber 19897-44-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,8,9 and 7 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 19897-44:
(7*1)+(6*9)+(5*8)+(4*9)+(3*7)+(2*4)+(1*4)=170
170 % 10 = 0
So 19897-44-0 is a valid CAS Registry Number.

Diterpenoid carboxylic acid anhydrides of the abietane, pimarane, and isopimarane series

Bardyshev

, p. 41 - 55 (2007/10/03)

Methods were developed for preparation of diterpenoid carboxylic acid anhydrides of the abietane, pimarane, and isopimarane series, the corresponding mixed anhydrides, and mixed anhydrides derived from resin acids and organic or inorganic acids. The resulting anhydrides sharply differ from the parent acids in physical properties; their thermal reactions and isomerizations and the rates of formation and hydrolysis were studied. The data obtained were used to develop new procedures for separation of anhydride mixtures into pure components. Reactions of abietic anhydride with some nucleophilic reagents gave the corresponding esters, ketones, amides, etc. Commercial samples of pine wood resins (gum rosin and tallic rosin) were shown to contain a small amount (0.2%) of diterpenoid anhydride mixtures.
