Check Digit Verification of cas no

The CAS Registry Mumber 1377585-56-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,7,5,8 and 5 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1377585-56:
(9*1)+(8*3)+(7*7)+(6*7)+(5*5)+(4*8)+(3*5)+(2*5)+(1*6)=212
212 % 10 = 2
So 1377585-56-2 is a valid CAS Registry Number.

Sulfoximines: A reusable directing group for chemo-and regioselective ortho C-H oxidation of arenes

Yadav, M. Ramu,Rit, Raja K.,Sahoo, Akhila K.

supporting information; experimental part, p. 5541 - 5545 (2012/06/01)

Sulfoximines direct: A new protocol for the chemo-and regioselective ortho C-H acetoxylation of arenes in N-benzoylated sulfoximines is reported. The sulfoximine directing group is easily detached from the C-H oxidation product through acid-promoted hydrolysis, isolated, and reused (see scheme). The meta-substituted phenols are synthesized following this strategy and the stereointegrity of the sulfoximine is preserved in this transformation. C(sp3)-H acetoxylation of the methyl group is also demonstrated.
