Check Digit Verification of cas no

The CAS Registry Mumber 855140-42-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,5,1,4 and 0 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 855140-42:
(8*8)+(7*5)+(6*5)+(5*1)+(4*4)+(3*0)+(2*4)+(1*2)=160
160 % 10 = 0
So 855140-42-0 is a valid CAS Registry Number.

Magnetic mesoporous poly-melamine–formaldehyde: an efficient and recyclable catalyst for straightforward one-pot synthesis of imidazo[1,2-a]pyridines

Heydari, Mohammad,Azizi, Najmedin,Mirjafari, Zohreh,Hashemi, Mohammad Mahmoudi

, p. 2357 - 2363 (2019/06/28)

Abstract: Magnetically separable mesoporous poly-melamine–formaldehyde nanocomposite (Fe3O4@mPMF) has been synthesized and characterized by FTIR spectroscopy, SEM, XRD spectroscopy and EDS. The magnetically separable Fe3O

A facile protocol for the synthesis of 3-aminoimidazo-fused heterocycles via the Groebke-Blackburn-Bienayme reaction under catalyst-free and solvent-free conditions

Vidyacharan, Shinde,Shinde, Anand H.,Satpathi, Bishnupada,Sharada, Duddu S.

supporting information, p. 1168 - 1175 (2014/03/21)

A one-pot catalyst, solvent, work-up and column free synthesis of 3-aminoimidazo-fused heterocycles by a three-component reaction of a 2-aminoheterocycle, aldehyde, and isocyanide is presented. This efficient and green protocol has the advantages of environmental friendliness, high yields and operational simplicity.
