Check Digit Verification of cas no

The CAS Registry Mumber 1155369-72-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,5,5,3,6 and 9 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1155369-72:
(9*1)+(8*1)+(7*5)+(6*5)+(5*3)+(4*6)+(3*9)+(2*7)+(1*2)=164
164 % 10 = 4
So 1155369-72-4 is a valid CAS Registry Number.

Efficient solvent- and metal-free Sonogashira protocol catalysed by 1,4-diazabicyclo(2.2.2) octane (DABCO)

Luque, Rafael,MacQuarrie, Duncan J.

, p. 1627 - 1632 (2009)

An efficient metal-free Sonogashira coupling protocol catalysed by DABCO is reported, where very good conversions and selectivities to the cross-coupling product were obtained under mild reaction conditions. The reported solvent-, phosphane- and metal-free protocol, that uses a cheap base as catalyst, considerably improves the green credentials of the reaction.
