131262-21-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131262-21-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,2,6 and 2 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 131262-21:
(8*1)+(7*3)+(6*1)+(5*2)+(4*6)+(3*2)+(2*2)+(1*1)=80
80 % 10 = 0
So 131262-21-0 is a valid CAS Registry Number.

Efficient and stereoselective cross-coupling with highly substituted alkenylsilanols
Denmark, Scott E,Pan, Weitao
, p. 98 - 104 (2002)
Highly substituted alkenylsilanols (1), readily prepared from commercially available simple starting materials, are efficiently coupled with aryl or alkenyl halides in the presence of tetrabutylammonium fluoride (TBAF) and a palladium(0) catalyst. Yields
