Check Digit Verification of cas no

The CAS Registry Mumber 1270893-40-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,7,0,8,9 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1270893-40:
(9*1)+(8*2)+(7*7)+(6*0)+(5*8)+(4*9)+(3*3)+(2*4)+(1*0)=167
167 % 10 = 7
So 1270893-40-7 is a valid CAS Registry Number.

Gold(i)-catalyzed cross-coupling reactions of aryldiazonium salts with organostannanes

Akram, Manjur O.,Shinde, Popat S.,Chintawar, Chetan C.,Patil, Nitin T.

, p. 2865 - 2869 (2018)

Gold(i)-catalyzed cross-coupling reactions of aryldiazonium salts with organostannanes are described. This redox neutral strategy offers an efficient approach to diverse biaryls, vinyl arenes and arylacetylenes. Monitoring the reaction with NMR and ESI-MS provided strong evidence for the in situ formation of Ph3PAuIR (R = aryl, vinyl and alkynyl) species which is crucial for the activation of aryldiazonium salts.
