Check Digit Verification of cas no

The CAS Registry Mumber 438219-37-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,8,2,1 and 9 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 438219-37:
(8*4)+(7*3)+(6*8)+(5*2)+(4*1)+(3*9)+(2*3)+(1*7)=155
155 % 10 = 5
So 438219-37-5 is a valid CAS Registry Number.

Iridium-catalyzed 1,3-hydrogen shift/chlorination of allylic alcohols

Ahlsten, Nanna,Gomez, Antonio Bermejo,Martin-Matute, Belen

, p. 6273 - 6276 (2013/07/05)

Tandem: Allylic alcohols react with N-chlorosuccinimide (NCS) in a tandem 1,3-H shift/C-Cl bond formation leading to α-chloroketones and α-chloroaldehydes. The reactions proceed with complete selectivity to give single constitutional isomers of monochlorinated carbonyl compounds. The utility of the transformation is illustrated by the straightforward synthesis of 4,5-disubstituted 2-aminothiazoles from allylic alcohols. Copyright
