Check Digit Verification of cas no

The CAS Registry Mumber 167967-07-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,7,9,6 and 7 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 167967-07:
(8*1)+(7*6)+(6*7)+(5*9)+(4*6)+(3*7)+(2*0)+(1*7)=189
189 % 10 = 9
So 167967-07-9 is a valid CAS Registry Number.

Pd-Catalyzed Carbonylation of Vinyl Triflates to Afford α,β-Unsaturated Aldehydes, Esters, and Amides under Mild Conditions

Zhang, Shaoke,Neumann, Helfried,Beller, Matthias

, p. 3528 - 3532 (2019/05/24)

An efficient and general protocol for the synthesis of α,β-unsaturated aldehydes, esters, and amides via carbonylation of vinyl triflates including derivatives of camphor, ketoisophorone, verbenone, and pulegone was developed. Crucial for these transformations is the use of a specific palladium catalyst containing a pyridyl-substituted dtbpx-type ligand. This procedure also allows for an easy access of dicarbonylated products from the corresponding ketones.

Oxazoline N-oxide-mediated [2+3] cycloadditions: New access to quaternary asymmetric centres

Collon, Stephane,Kouklovsky, Cyrille,Langlois, Yves

, p. 3566 - 3572 (2007/10/03)

Cycloadditions between camphor-derived oxazoline N-oxide 1 and dipolarophiles 5 or 8 afforded adducts 6 and 9, respectively, with almost complete regio- and stereoselectivity depending on the substitution patterns of the dipolarophiles. Wiley-VCH Verlag GmbH, 69451 Weinheim, Germany, 2002.
