Check Digit Verification of cas no
The CAS Registry Mumber 821-98-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,2 and 1 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 821-98:
(5*8)+(4*2)+(3*1)+(2*9)+(1*8)=77
77 % 10 = 7
So 821-98-7 is a valid CAS Registry Number.

Tergal Gland Secretion of the Rove Beetle Aleochara pseudochrysorrhoa (Staphylinidae: Aleocharinae): Chemical Composition and Biological Roles
da Silva, Maycon R.,Vidal, Diogo M.,Figueiredo, Leonardo,Bandeira, Pamela T.,Bergmann, Jan,Zarbin, Paulo H. G.

Aleochara pseudochrysorrhoa has a glandular complex known as the tergal gland. Generally, the tergal gland secretion (TGS) has been described to have defensive function, but some reports point to a possible secondary function of this complex. For example, the TGS of the related species A. curtula has been demonstrated to possess an important role in intraspecies communication. In this work, we describe the chemical composition of the TGS of A. pseudochrysorrhoa males and females. Eleven compounds were identified based on GC/MS and GC-FT-IR analyses, retention indexes and derivatization products. Furthermore, a brief study regarding the biological function of the TGS in mating behavior is provided, in which the stimulation of male grasping response reaction by female TGS proved to be dependent on concentration.

Alkyltriphenylphosphonium salts react with saturated α,β-ethylenic, α,β-acetylenic, and cyclic aliphatic aldehydes when heated with solid potassium carbonate to form the corresponding alkenes with preparative yields.The reaction is cis-stereoselective with saturated aldehydes and cis-stereospecific with unsaturated aldehydes.
