Check Digit Verification of cas no

The CAS Registry Mumber 562813-17-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,6,2,8,1 and 3 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 562813-17:
(8*5)+(7*6)+(6*2)+(5*8)+(4*1)+(3*3)+(2*1)+(1*7)=156
156 % 10 = 6
So 562813-17-6 is a valid CAS Registry Number.

Sonogashira coupling reaction with diminished homocoupling

Elangovan, Arumugasamy,Wang, Yu-Hsiang,Ho, Tong-Ing

, p. 1841 - 1844 (2007/10/03)

(Matrix presented) The side product from homocoupling reaction of two terminal acetylenes in the Sonogashira reaction can be reduced to about 2% using an atmosphere of hydrogen gas diluted with nitrogen or argon. Terminal arylethynes, diarylethynes, and a few new arylpyridylethynes with donor substituents have been synthesized in very good yields. Comparative control experiments suggest that the homocoupling yield is determined by concentration of both catalyst and oxygen.
