Check Digit Verification of cas no

The CAS Registry Mumber 78808-51-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,8,0 and 8 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 78808-51:
(7*7)+(6*8)+(5*8)+(4*0)+(3*8)+(2*5)+(1*1)=172
172 % 10 = 2
So 78808-51-2 is a valid CAS Registry Number.

Highly stereocontrolled synthesis of fluorinated 2,6-trans dihydropyrans via Prins cyclization

Luo, Hai-Qing,Hu, Xu-Hong,Loh, Teck-Peng

, p. 1041 - 1043 (2010)

A highly efficient method for the synthesis of fluorinated 2,6-trans dihydropyrans via BF3·Et2O-promoted Prins cyclization of allenic alcohols and aldehydes is developed. Various 2,6-trans fluorodihydropyrans are obtained in moderate

A CONVENIENT SYNTHESIS OF α-HYDROXYALLENES BY THE REACTION OF PROPARGYL IODIDES WITH ALDEHYDES IN THE PRESENCE OF STANNOUS HALIDE

Mukaiyama, Teruaki,Harada, Taira

, p. 621 - 624 (2007/10/02)

In the presence of stannous halide, propargyl iodides react with aldehydes in an aprotic solvent to yield α-hydroxyallenes as major products, particularly in the cases of γ-substituted propargyl iodides, along with β-hydroxyacetylenes.
