Check Digit Verification of cas no
The CAS Registry Mumber 250-91-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,5 and 0 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 250-91:
(5*2)+(4*5)+(3*0)+(2*9)+(1*1)=49
49 % 10 = 9
So 250-91-9 is a valid CAS Registry Number.

, p. 1770 - 1778 (2007/10/02)
Reaction of furopyrroles and their benzo analogues with dimethyl butynedioate and ethyl propynoate were investigated.The reaction course is influenced by substituents on the system.Products of cycloaddition to the furan or pyrrole nucleus as well as products of Michael addition to the benzofuropyrrole system have been found.The structure of the products has been proven by 1H NMR and 13C NMR spectroscopy.
