Check Digit Verification of cas no
The CAS Registry Mumber 3744-11-4 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, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 3744-11:
(6*3)+(5*7)+(4*4)+(3*4)+(2*1)+(1*1)=84
84 % 10 = 4
So 3744-11-4 is a valid CAS Registry Number.

Triarylsulfonium bromides were synthesized by the reaction of diaryl sulfoxides with aryl Grignard reagents in the presence of TMSC1 followed by treatment with HBr aqueous solution. Triarylsulfonium bromides bearing three identical substituents on sulfur atom were synthesized by the treatment of dimethyl sulfite or thionyl chloride with 5 equivalents of Grignard reagent in the presence of TMSC1.
