Check Digit Verification of cas no

The CAS Registry Mumber 55279-82-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,2,7 and 9 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 55279-82:
(7*5)+(6*5)+(5*2)+(4*7)+(3*9)+(2*8)+(1*2)=148
148 % 10 = 8
So 55279-82-8 is a valid CAS Registry Number.

Preparation et proprietes de quelques sulfures de phospholes fonctionnels

Mathey

, p. 3127 - 3137 (1974)

tBuLi with 1-phenyl 3,4-dimethyl phosphole sulfide 1 in THF, gives a mesomeric anion 4. With aldehydes and ketones, this anion leads to methyl-substituted phospholes (6 and 9), 2-substituted phospholes (8) or 2-substituted 3-methylene phosphol 4-enes (5 and 7). With CO2 and CH3COOEt a 2-phosphole carboxylic acid 11 and a 2-acetyl phosphole 10 are obtained, respectively. The spectra of the 2-substituted phospholes are studied in some detail. Some of their chemical properties (dimerization, dissociation and tert-butylation) are also described.
