Check Digit Verification of cas no
The CAS Registry Mumber 3349-65-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,3,4 and 9 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 3349-65:
(6*3)+(5*3)+(4*4)+(3*9)+(2*6)+(1*5)=93
93 % 10 = 3
So 3349-65-3 is a valid CAS Registry Number.

2- and 2,3-Substituted pyrroles are readily synthesized in a one-pot procedure from ketones, hydroxylamine hydrochloride, and 1,2-dichloroethane in the KOH/DMSO system (120 °C, 2-4 h), the yields of pyrroles ranging 11-85%. Aliphatic, cycloaliphatic, aromatic, and heteroaromatic ketones tolerate the reaction conditions.
