Check Digit Verification of cas no

The CAS Registry Mumber 1571097-98-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,7,1,0,9 and 7 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1571097-98:
(9*1)+(8*5)+(7*7)+(6*1)+(5*0)+(4*9)+(3*7)+(2*9)+(1*8)=187
187 % 10 = 7
So 1571097-98-7 is a valid CAS Registry Number.

A cyclic merocyanine UV-A absorber: Mechanism of formation and crystal structure

Winkler, Barbara,Hoeffken, Hans Wolfgang,Eichin, Kai,Houy, Wolfgang

, p. 1749 - 1751 (2014)

The product of the reaction of 3-(3-methoxypropylamino)cyclohex-2-en-1-one and diethylsulfate has been crystallized and its structure has been determined by X-ray crystallography. The study allowed insight into the formation mechanism of cyclic merocyanine UV absorbers. X-ray diffraction analysis of the merocyanine product made it possible to define the E/Z-stereoconfiguration.
