Check Digit Verification of cas no

The CAS Registry Mumber 1315475-93-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,5,4,7 and 5 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1315475-93:
(9*1)+(8*3)+(7*1)+(6*5)+(5*4)+(4*7)+(3*5)+(2*9)+(1*3)=154
154 % 10 = 4
So 1315475-93-4 is a valid CAS Registry Number.

A Suzuki-type cross-coupling reaction of arylacetylene halides with arylboronic acids

Shi, Yu,Li, Xiaoyu,Liu, Jianhui,Jiang, Wenfeng,Sun, Licheng

, p. 514 - 520 (2011)

A PdCl2-catalyzed direct alkynylation of arylboronic acids to give diarylacetylenes is described. The optimal conditions using PdCl 2 as catalyst, MeOH-PhMe-H2O as solvent and K 2CO3 as base effectively suppressed the formation of homo-coupling product and afforded moderate to good yield of the desired unsymmetrical coupling product. This reaction represents a Suzuki-type sp 2(C-B)-sp(C-X) cross-coupling. Copyright
