Check Digit Verification of cas no

The CAS Registry Mumber 149511-82-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,5,1 and 1 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 149511-82:
(8*1)+(7*4)+(6*9)+(5*5)+(4*1)+(3*1)+(2*8)+(1*2)=140
140 % 10 = 0
So 149511-82-0 is a valid CAS Registry Number.

Organic template-free synthesis of zeolite Y nanoparticle assemblies and their application in the catalysis of the Ritter reaction

Tang, Ting,Zhang, Lei,Dong, Hai,Fang, Zhongxue,Fu, Wenqian,Yu, Quanyong,Tang, Tiandi

, p. 7711 - 7717 (2017)

Zeolite Y nanoparticle assemblies (Y-NA) with a mesoporous structure were directly synthesized at 75?°C for 16 h without adding any organic templates. The changes in structure, morphology and textural parameters of the materials obtained after different crystallization times were investigated via powder X-ray diffraction (XRD), infrared spectroscopy (IR), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and N2-sorption. The results show that Y-NA had a micro-mesoporous structure composed of highly crystalline particle assemblies with sizes of 400-900 nm. The H-form Y-NA (HY-NA) is strongly acidic, and exhibits a good catalytic performance in the Ritter reaction, as compared with the H-form microporous zeolite Y and mesoporous zeolite ZSM-5.
