Check Digit Verification of cas no

The CAS Registry Mumber 1173163-85-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,3,1,6 and 3 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1173163-85:
(9*1)+(8*1)+(7*7)+(6*3)+(5*1)+(4*6)+(3*3)+(2*8)+(1*5)=143
143 % 10 = 3
So 1173163-85-3 is a valid CAS Registry Number.

Transition-metal-catalyzed regioselective aroyl- and trifluoro- acetylthiolation of alkynes using thioesters

Minami, Yasunori,Kuniyasu, Hitoshi,Miyafuji, Kiyoshi,Kambe, Nobuaki

supporting information; experimental part, p. 3080 - 3082 (2009/12/01)

Intermolecular CO-retained carbothiolation of alkynes using thioesters took place to afford β-SR substituted enone derivatives; the choice of catalyst (Pd(dba)2-dppe) and the introduction of a CF3 group into the thioesters are the key to achieving the transformation.
