Check Digit Verification of cas no

The CAS Registry Mumber 157668-04-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,6,6 and 8 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 157668-04:
(8*1)+(7*5)+(6*7)+(5*6)+(4*6)+(3*8)+(2*0)+(1*4)=167
167 % 10 = 7
So 157668-04-7 is a valid CAS Registry Number.

Photoinduced electron transfer (PET) promoted cyclisations of 1-[N-alkyl-N-(trimethylsilyl)methyl]amines tethered to proximate olefin: Mechanistic and synthetic perspectives

Pandey, Ganesh,Devi Reddy,Kumaraswamy

, p. 8185 - 8194 (2007/10/02)

Upon PET reaction, amines of type 1 undergo efficient cyclisations to produce pyrrolidines and piperidines. Mechanistically, involvement of delocalised α-silylmethyl amine radical cation as reactive intermediate in such cyclisations are described.
