Check Digit Verification of cas no

The CAS Registry Mumber 1431660-25-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,1,6,6 and 0 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1431660-25:
(9*1)+(8*4)+(7*3)+(6*1)+(5*6)+(4*6)+(3*0)+(2*2)+(1*5)=131
131 % 10 = 1
So 1431660-25-1 is a valid CAS Registry Number.

Dearomative radical spirocyclization from N-ce: Raghubenzyltrichloroacetamides revisited using a copper(I)-mediated atom transfer reaction leading to 2-azaspiro[4.5]decanes

Diaba, Fa?za,Montiel, Juan A.,Martínez-Laporta, Agustín,Bonjoch, Josep

, p. 2619 - 2622 (2013/06/05)

An atom transfer radical dearomatizing spirocyclization from N-benzyltrichloroacetamides using CuCl regioselectively leads to 2-azaspiro[4.5]decadienes, in which the labile allylic chlorine atom is easily replaced by a hydroxyl group in aqueous medium or by quenching with methanol or allylamine. After oxidation of the target compound, the N-tert-butyl group can be removed from the resulting spirocyclohexanedienone.
