Check Digit Verification of cas no

The CAS Registry Mumber 1044572-91-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,4,5,7 and 2 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1044572-91:
(9*1)+(8*0)+(7*4)+(6*4)+(5*5)+(4*7)+(3*2)+(2*9)+(1*1)=139
139 % 10 = 9
So 1044572-91-9 is a valid CAS Registry Number.

Meta- and para-difunctionalization of arenes via a sulfoxide-magnesium exchange reaction

Rauhut, Christian B.,Melzig, Laurin,Knochel, Paul

supporting information; experimental part, p. 3891 - 3894 (2009/07/01)

(Chemical Equation Presented) The aryl sulfoxide moiety (ArSO) allows an expedient two-step meta-, para-difunctionalization of readily available diaryl sulfoxides. In the first step, the sulfoxide plays the role of a directing metalation group. In the second step, triggered by i-PrMgCl·LiCl, it becomes a leaving group and undergoes a regioselective sulfoxide-magnesium exchange.
