Check Digit Verification of cas no

The CAS Registry Mumber 126708-68-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,7,0 and 8 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 126708-68:
(8*1)+(7*2)+(6*6)+(5*7)+(4*0)+(3*8)+(2*6)+(1*8)=137
137 % 10 = 7
So 126708-68-7 is a valid CAS Registry Number.

Use of the 2-Pyridinesulfonyloxy Leaving Group for the Fast Copper-Catalyzed Coupling Reaction at Secondary Alkyl Carbons with Grignard Reagents

Shinohara, Riku,Morita, Masao,Ogawa, Narihito,Kobayashi, Yuichi

supporting information, p. 3247 - 3251 (2019/05/10)

Investigation of the copper-catalyzed coupling reaction of 2-pyridinesulfonates with Grignard reagents revealed that reactions with catalytic Cu(OTf)2 were completed in 40 min. The results differed from those of the previous CuI-catalyzed reactions of tosylates in the presence of additives (LiOMe and TMEDA) for 12-24 h. It was shown that the preferred coordination of the leaving group to the reagents accelerated the reaction. Successful reagents were MeMgCl and other RMgX. Complete inversion was established.
