1333913-81-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1333913-81-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,3,9,1 and 3 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1333913-81:
(9*1)+(8*3)+(7*3)+(6*3)+(5*9)+(4*1)+(3*3)+(2*8)+(1*1)=147
147 % 10 = 7
So 1333913-81-7 is a valid CAS Registry Number.

Photochromism and mechanism of pyrazolones in crystals: Structural variations directly observed by X-ray diffraction

Guo, Jixi,Jia, Dianzeng,Liu, Lang,Yuan, Hui,Guo, Mingxi,Wu, Dongling,Li, Feng

, p. 12202 - 12205 (2011)

Structural changes of photochromic pyrazolones were first verified by an X-ray crystallographic method directly. A tautomeric transformation between enol and keto form isomers occurs, accompanied by proton transfer during the photochromic processes.
