Check Digit Verification of cas no

The CAS Registry Mumber 180140-18-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,0,1,4 and 0 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 180140-18:
(8*1)+(7*8)+(6*0)+(5*1)+(4*4)+(3*0)+(2*1)+(1*8)=95
95 % 10 = 5
So 180140-18-5 is a valid CAS Registry Number.

Umpoled Vilsmeier reagents. The chemistry of aminochlorocarbenes derived from Vilsmeier reagents by the action of bases

Cheng, Ying,Goon, Simon,Meth-Cohn, Otto

, p. 1619 - 1625 (2007/10/03)

Vilsmeier reagents such as N-methyl-N-phenylchloroiminium chloride are readily deprotonated by tert-amines even in POCl3 solution. The resulting transient intermediates, aminochlorocarbenes, are nucleophilic (i.e. umpoled Vilsmeier reagents) and are trapped with electrophiles. In this way dimers [1,2-bis(N-methylanilino)-1,2-dichloroethanes] 3, 'trimers' (indolo[3,2-b]quinolininium chlorides) 4 and 5, 'tetramers' (2,2′-bis-indoles) 11 and isatins 9 and 10 are accessible in one-pot processes from the formanilide.
