1-Methyl-2-sulfo-quinolinium betaine, also known as quinolinium-1-methyl-2-sulfonate, is a chemical compound with the molecular formula C9H12N+O3S-. It is a derivative of quinolinium, a heterocyclic compound consisting of a quinoline ring with a positively charged nitrogen atom. The molecule features a methyl group attached to the nitrogen atom and a sulfonate group (-SO3-) at the 2-position of the quinoline ring. 1-methyl-2-sulfo-quinolinium betaine is often used as a counterion in the synthesis of various quinolinium-based salts and has potential applications in the field of organic chemistry, particularly in the development of dyes, pigments, and other functional materials. Its unique structure and properties make it an interesting subject for further research and exploration in chemical synthesis and material science.

Check Digit Verification of cas no

The CAS Registry Mumber 4329-90-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,2 and 9 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4329-90:
(6*4)+(5*3)+(4*2)+(3*9)+(2*9)+(1*0)=92
92 % 10 = 2
So 4329-90-2 is a valid CAS Registry Number.
