Check Digit Verification of cas no
The CAS Registry Mumber 1777-03-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,7 and 7 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1777-03:
(6*1)+(5*7)+(4*7)+(3*7)+(2*0)+(1*3)=93
93 % 10 = 3
So 1777-03-3 is a valid CAS Registry Number.

Bulky trialkylsilyl acetylenes in the Cadiot-Chodkiewicz cross-coupling reaction
Marino, Joseph P.,Nguyen, Hanh Nho
, p. 6841 - 6844 (2007/10/03)
Bulky trialkylsilyl-protected alkynes such as triethylsilyl (TES), tert-butyldimethylsilyl (TBS), and tri-isopropylsilyl (TIPS) acetylenes underwent the Cadiot-Chodkiewicz cross-coupling reaction with different bromoalkynes to form a variety of synthetically useful unsymmetrical diynes in good yields. The diyne alcohol 10 was transformed regio- and stereoselectively into enynes by hydrotelluration, carbometalation, and reduction reactions.
