1257084-13-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1257084-13-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,7,0,8 and 4 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1257084-13:
(9*1)+(8*2)+(7*5)+(6*7)+(5*0)+(4*8)+(3*4)+(2*1)+(1*3)=151
151 % 10 = 1
So 1257084-13-1 is a valid CAS Registry Number.

N,N,N',N'-tetrabromobenzene-1,3-disulfonamide and poly(N,N’-dibromo-N-ethyl-benzene-1,3-disulfonamide) were used as efficient catalysts for one-pot synthesis of new quinazoline derivatives from various aldehydes, 2-amino-benzophenone, and ammonium acetate

Catalyst-free synthesis of quinazoline derivatives using low melting sugar-urea-salt mixture as a solvent

Zhang, Zhan-Hui,Zhang, Xiao-Nan,Mo, Li-Ping,Li, Yong-Xiao,Ma, Fei-Ping

experimental part, p. 1502 - 1506 (2012/06/04)

Low melting mixture of maltose-dimethylurea (DMU)-NH4Cl was found to be an inexpensive, non-toxic, easily biodegradable and effective reaction medium in the catalyst-free synthesis of quinazoline derivatives. This simple and efficient method fu
