17582-54-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 17582-54-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,5,8 and 2 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 17582-54:
(7*1)+(6*7)+(5*5)+(4*8)+(3*2)+(2*5)+(1*4)=126
126 % 10 = 6
So 17582-54-6 is a valid CAS Registry Number.

Mechanisms for the cleavage of carbon-tin bonds. VI. A kinetic and stereochemical study of the halodemetallation of cyclopropyltrialkyltins: the solvent effect

Gielen,Baekelmans,Nasielski

, p. 329 - 339 (2008/10/08)

The bimolecular halodemetallation of substituted cyclopropyltrialkyltins is stereospecific, and proceeds with retention of the configuration at carbon in methanol, acetic acid and chlorobenzene. The kinetic study confirms the hypothesis which was based on results for the R′SnR3 series, and shows the participation of the ring orbitals in the rate determining step of the reaction. A study of the selectivity in various media has revealed a surprising solvent effect.
