Check Digit Verification of cas no

The CAS Registry Mumber 20006-79-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,0,0 and 6 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 20006-79:
(7*2)+(6*0)+(5*0)+(4*0)+(3*6)+(2*7)+(1*9)=55
55 % 10 = 5
So 20006-79-5 is a valid CAS Registry Number.

Factors that influence the spectroscopic properties of 1,3-bis[p-substituted-(phenylamino)]squaraines

Kabatc, Janina,Kostrzewska, Katarzyna,Orze?, ?ukasz

, p. 226 - 232 (2016)

The spectroscopic characteristics of a series of ten aminosquaraine dyes that differ in the type of chemical substituent at the p-position of the phenyl ring were investigated. The effect of solvent on the properties of the dyes in their ground and excite

The synthesis and spectroscopic studies of new aniline-based squarylium dyes

Jurek, Katarzyna,Kabatc, Janina,Kostrzewska, Katarzyna

, p. 273 - 279 (2016/07/06)

The synthesis and spectroscopic properties of series of new aniline-based squarine dyes have been presented. The effect of solvent polarity, hydrogen bonding and substituent on spectroscopic properties of 1,3-bis(phenylamino)squarine (SQG1), 1,3-bis(4-bro

Efficient microwave-assisted preparation of squaric acid monoamides in water

Lopez, Carlos,Vega, Manuel,Sanna, Elena,Rotger, Carmen,Costa, Antoni

, p. 7249 - 7253 (2013/07/05)

Squaric acid monoamides (SQAMs) were prepared via microwave-enhanced direct reaction of amines with squaric acid in yields ranging from 41 to 92%. These compounds are strong acids, with pKa values ranging from 0.9 to 2.0 as determined by spectrophotometric titration in representative cases. The Royal Society of Chemistry 2013.
