(Z)-2-benzylidene-3,5-dimethoxy-2H-pyrrole is a complex organic chemical compound with the molecular formula C14H15NO2. It is characterized by a pyrrole ring, which is a five-membered aromatic ring containing one nitrogen atom, and two methoxy groups attached to the 3rd and 5th positions of the pyrrole. The compound also features a benzylidene group (a phenyl group double-bonded to a carbonyl group) at the 2nd position of the pyrrole ring. This specific geometric isomer, denoted by the "Z" prefix, indicates that the substituents on the double bond are on the same side, following the Cahn-Ingold-Prelog priority rules. (Z)-2-benzylidene-3,5-dimethoxy-2H-pyrrole is known for its potential applications in the synthesis of various pharmaceuticals and agrochemicals, as well as its role as an intermediate in organic synthesis.

Check Digit Verification of cas no

The CAS Registry Mumber 87643-20-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,6,4 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 87643-20:
(7*8)+(6*7)+(5*6)+(4*4)+(3*3)+(2*2)+(1*0)=157
157 % 10 = 7
So 87643-20-7 is a valid CAS Registry Number.
