Check Digit Verification of cas no

The CAS Registry Mumber 945038-56-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,5,0,3 and 8 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 945038-56:
(8*9)+(7*4)+(6*5)+(5*0)+(4*3)+(3*8)+(2*5)+(1*6)=182
182 % 10 = 2
So 945038-56-2 is a valid CAS Registry Number.

Straightforward synthesis of 2-aryl-1-alkynylphosphonates and arylpropiolates

Lecercle, Delphine,Mothes, Celine,Taran, Frederic

, p. 1301 - 1311 (2007)

A protocol for the direct cross coupling of trialkylsilyl-alkynes bearing electron-withdrawing groups and aryl halides using a Pd/Ag catalytic system is described. The procedure allows the straightforward synthesis of a variety of alkynylphosphonates and aryl propiolates derivatives in good yields. Copyright Taylor & Francis Group, LLC.
