Check Digit Verification of cas no

The CAS Registry Mumber 1267636-78-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,7,6,3 and 6 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1267636-78:
(9*1)+(8*2)+(7*6)+(6*7)+(5*6)+(4*3)+(3*6)+(2*7)+(1*8)=191
191 % 10 = 1
So 1267636-78-1 is a valid CAS Registry Number.

Development of a Rhodium(II)-Catalyzed Chemoselective C(sp3)-H Oxygenation

Lin, Yun,Zhu, Lei,Lan, Yu,Rao, Yu

supporting information, p. 14937 - 14942 (2015/10/19)

We report the first example of RhII-catalyzed chemoselective double C(sp3)-H oxygenation, which can directly transform various toluene derivatives into highly valuable aromatic aldehydes with great chemoselectivity and practicality. The critical combination of catalyst Rh(OAc)2, oxidant Selectfluor, and solvents of TFA/TFAA promises the successful delivery of the oxidation with satisfactory yields. A possible mechanism involving a unique carbene-Rh complex is proposed, and has been supported by both experiments and theoretical calculations.
