Check Digit Verification of cas no

The CAS Registry Mumber 19962-41-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,9,6 and 2 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 19962-41:
(7*1)+(6*9)+(5*9)+(4*6)+(3*2)+(2*4)+(1*1)=145
145 % 10 = 5
So 19962-41-5 is a valid CAS Registry Number.

Indium-mediated regioselective synthesis of ketones from arylstannanes under solvent-free ultrasound irradiation

Lo Fiego, Marcos J.,Badajoz, Mercedes A.,Domini, Claudia,Chopa, Alicia B.,Lockhart, María T.

, p. 826 - 832 (2013/03/14)

The solvent-free indium-promoted reaction of alkanoyl chlorides with sterically and electronically diverse arylstannanes is a simple and direct method for the regioselective synthesis of primary, secondary and tertiary alkyl aryl ketones in good to excellent isolated yields (42-84%) under mild and neutral conditions. The protocol is also adequate for the synthesis of aryl vinyl ketones. Reaction times are drastically reduced (from 3-32 h to 10-70 min) under ultrasonic irradiation. Evidences for the involvement of a homolytic aromatic ipso-substitution mechanism, in which indium metal acts as radical initiator, are presented. It is possible the transference of two aryl groups from tin, thus improving effective mass yield, working with diarylstannanes as starting substrates.
