Check Digit Verification of cas no

The CAS Registry Mumber 1427778-16-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,7,7,7 and 8 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1427778-16:
(9*1)+(8*4)+(7*2)+(6*7)+(5*7)+(4*7)+(3*8)+(2*1)+(1*6)=192
192 % 10 = 2
So 1427778-16-2 is a valid CAS Registry Number.

Subtle electronic effects in metal-free rearrangement of allenic alcohols

Sabbasani, Venkata R.,Mamidipalli, Phani,Lu, Huijie,Xia, Yuanzhi,Lee, Daesung

, p. 1552 - 1555 (2013/06/26)

A general and stereoselective rearrangement of allenic alcohols to (E,E)-1,3-dien-2-yl triflates and chlorides was developed under metal-free conditions. Subtle electronic effects of the alkyl and aryl substituents on the carbon bearing the hydroxyl group has a profound impact on the reaction rate and efficiency such that vinyl triflates were obtained from electron-deficient substrates and trimethylsilyl triflate whereas vinyl chlorides were generated with an electron-rich substrate and trimethylsilyl chloride.
