Check Digit Verification of cas no

The CAS Registry Mumber 14629-53-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,6,2 and 9 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 14629-53:
(7*1)+(6*4)+(5*6)+(4*2)+(3*9)+(2*5)+(1*3)=109
109 % 10 = 9
So 14629-53-9 is a valid CAS Registry Number.

Methyllithium-promoted Wittig rearrangements of α-alkoxysilanes

Maleczka Jr., Robert E.,Geng, Feng

, p. 1115 - 1118 (2008/02/09)

(matrix presented) The Wittig rearrangements of α-alkoxysilanes, promoted by the action of methyllithium were studied. Depending on both the substrate and reaction conditions employed, [2,3]-, [1,2]-, or [1,4]-Wittig rearrangements can be realized. These rearrangements were shown to be initiated by either Si/Li exchange or deprotonation a to the silane. Furthermore the sigmatropic shifts can often be followed by other synthetically useful in situ chemical events.
