330957-88-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 330957-88-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,0,9,5 and 7 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 330957-88:
(8*3)+(7*3)+(6*0)+(5*9)+(4*5)+(3*7)+(2*8)+(1*8)=155
155 % 10 = 5
So 330957-88-5 is a valid CAS Registry Number.

MCM-41@Schiff base-Co(OAc)2 as an efficient catalyst for the synthesis of pyran derivatives

Pan, Shiwei,Li, Puhui,Xu, Guihua,Guo, Jingchang,Ke, Libin,Xie, Canquan,Zhang, Zhoucai,Hui, Yonghai

, p. 1353 - 1371 (2019/11/20)

Heterogeneous ordered mesoporous silica materials catalyst, MCM-41@Schiff base-Co(AcO)2, reveals high catalytic performance within the synthesis of pyran derivatives using the multicomponent reaction of aldehydes, malononitrile and 2-naphthol (

Nano polypropylenimine dendrimer (DAB-PPI-G1): As a novel nano basic-polymer catalyst for one-pot synthesis of 2-amino-2-chromene derivatives

Maleki, Behrooz,Sheikh, Safoora

, p. 42997 - 43005 (2015/05/27)

The nano polypropylenimine dendrimer (DAB-PPI-G1) Lewis base catalyst was found to be a highly efficient and recoverable catalyst for the rapid and convenient synthesis of 2-amino-2-chromene derivatives through the three-component condensation of aromatic aldehydes, malononitrile or ethyl cyanoacetate and phenols under solvent-free conditions in excellent yields and short reaction times.
