Check Digit Verification of cas no

The CAS Registry Mumber 129222-25-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,2,2 and 2 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 129222-25:
(8*1)+(7*2)+(6*9)+(5*2)+(4*2)+(3*2)+(2*2)+(1*5)=109
109 % 10 = 9
So 129222-25-9 is a valid CAS Registry Number.

Sulfonamide-Trapping Reactions of Thermally Generated Benzynes

Wang, Yuanxian,Zheng, Lianyou,Hoye, Thomas R.

, p. 7145 - 7148 (2018)

Reactions of tethered, tertiary sulfonamides with thermally generated benzynes are reported. Typically, the N-S bonds in the substrates cleave, and saturated heterocycles [tetrahydroquinolines (n = 2) and indolines (n = 1)] are formed. The process is accompanied by either sulfonyl transfer or desulfonylation from a zwitterionic intermediate, with the favored pathway being largely dependent upon the size (5- vs 6-membered) of the N-containing ring in the zwitterion.
