Check Digit Verification of cas no

The CAS Registry Mumber 1416964-70-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,6,9,6 and 4 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1416964-70:
(9*1)+(8*4)+(7*1)+(6*6)+(5*9)+(4*6)+(3*4)+(2*7)+(1*0)=179
179 % 10 = 9
So 1416964-70-9 is a valid CAS Registry Number.

The gomberg-bachmann reaction for the arylation of anilines with aryl diazotates

Pratsch, Gerald,Wallaschkowski, Tina,Heinrich, Markus R.

supporting information, p. 11555 - 11559,5 (2012/12/12)

Simply aqueous sodium hydroxide is sufficient to exclude ionic side reactions and to prepare 2-aminobiphenyls from aryl diazotates and anilines through a new variant of the Gomberg-Bachmann reaction (see scheme). The metal-free reaction under basic conditions allows to exploit the highly radical-stabilizing effect of the aniline's free amino function for the first time, which leads to a so far unreached regioselectivity.
