Check Digit Verification of cas no

The CAS Registry Mumber 1421319-42-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,1,3,1 and 9 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1421319-42:
(9*1)+(8*4)+(7*2)+(6*1)+(5*3)+(4*1)+(3*9)+(2*4)+(1*2)=117
117 % 10 = 7
So 1421319-42-7 is a valid CAS Registry Number.

Ruthenium-catalyzed C-h oxygenation on aryl Weinreb amides

Yang, Fanzhi,Ackermann, Lutz

supporting information, p. 718 - 720 (2013/03/29)

Versatile ruthenium catalysts enabled unprecedented C-H bond oxygenations of aryl Weinreb amides with ample scope under exceedingly mild reaction conditions, thereby also giving access to valuable ortho-hydroxylated aldehydes. Mechanistic studies provided strong support for a kinetically relevant C-H bond activation.
