Sulfonium, (4-methylphenyl)diphenyl-, iodide, also known as 4-methylphenyldiphenylsulfonium iodide, is a chemical compound with the molecular formula C19H17IS. It is a salt derived from the sulfonium ion, which is a positively charged sulfur atom bonded to three organic groups. In this case, the three organic groups are two phenyl rings and a 4-methylphenyl group. The iodide ion (I-) is the counterion in this salt. Sulfonium, (4-methylphenyl)diphenyl-, iodide is often used as a reagent in organic synthesis, particularly in the formation of carbon-sulfur bonds and as a source of the phenylsulfenyl cation in electrophilic aromatic substitution reactions. It is also known for its potential applications in the synthesis of pharmaceuticals and agrochemicals.

Check Digit Verification of cas no

The CAS Registry Mumber 3744-09-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,7,4 and 4 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 3744-09:
(6*3)+(5*7)+(4*4)+(3*4)+(2*0)+(1*9)=90
90 % 10 = 0
So 3744-09-0 is a valid CAS Registry Number.
