Check Digit Verification of cas no

The CAS Registry Mumber 141223-29-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,2,2 and 3 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 141223-29:
(8*1)+(7*4)+(6*1)+(5*2)+(4*2)+(3*3)+(2*2)+(1*9)=82
82 % 10 = 2
So 141223-29-2 is a valid CAS Registry Number.

Facile synthesis of diarylsulfones from arenes and 3CdSO4·xH2O via mechanochemistry

Qin, Shuai,Zhang, Pu,Qin, Yu-Jun,Guo, Zhi-Xin

supporting information, (2020/01/06)

A variety of substituted diarylsulfones could be synthesized by simple arenes and 3CdSO4·xH2O in the presence of P2O5 under high-speed ball milling. It was suggest the aromatic sulfonation was performed by arene and in situ generated H2SO4, following-up by electrophilic substitution with another arene to give diarylsulfone.
