Check Digit Verification of cas no

The CAS Registry Mumber 1229971-87-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,9,9,7 and 1 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1229971-87:
(9*1)+(8*2)+(7*2)+(6*9)+(5*9)+(4*7)+(3*1)+(2*8)+(1*7)=192
192 % 10 = 2
So 1229971-87-2 is a valid CAS Registry Number.

Diversity-oriented synthesis of disubstituted alkenes using masked silanols

Sore, Hannah F.,Blackwell, David T.,MacDonald, Simon J. F.,Spring, David R.

, p. 2806 - 2809 (2010)

(Figure presented) The regio- and stereoselective synthesis and subsequent Hiyama cross coupling of pentafluorophenyldimethylvinylsilanes has been developed, thus providing a convenient and robust method for the diversity-oriented synthesis of (E)-, (Z)- and α-disubstituted alkenes from terminal alkynes. Pentafluorophenyldimethylvinylsilanes undergo cross-coupling reactions with excellent selectivity and in good yields, offering an attractive alternative to existing masked silanols.
