Check Digit Verification of cas no

The CAS Registry Mumber 1548411-64-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,4,8,4,1 and 1 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1548411-64:
(9*1)+(8*5)+(7*4)+(6*8)+(5*4)+(4*1)+(3*1)+(2*6)+(1*4)=168
168 % 10 = 8
So 1548411-64-8 is a valid CAS Registry Number.

Reactivity switch enabled by counterion: Highly chemoselective dimerization and hydration of terminal alkynes

Xu, Caixia,Du, Weiyuan,Zeng, Yi,Dai, Bin,Guo, Hao

, p. 948 - 951 (2014/03/21)

A counterion-controlled reactivity tuning in Pd-catalyzed highly chemoselective and regioselective dimerization and hydration of terminal alkynes is reported. The use of acetate as counterion favors the formation of an alkenyl alkynyl palladium intermediate which forms hitherto less reported 1,3-diaryl-substituted conjugated enynes after reductive elimination. Using chloride, which is a better leaving group, leads to anion exchange on the alkenylpalladium intermediate with hydroxide which after reductive elimination and tautomerization delivered the hydration products.
