Check Digit Verification of cas no

The CAS Registry Mumber 118893-13-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,8,9 and 3 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 118893-13:
(8*1)+(7*1)+(6*8)+(5*8)+(4*9)+(3*3)+(2*1)+(1*3)=153
153 % 10 = 3
So 118893-13-3 is a valid CAS Registry Number.

Photochemical Hydrogen Abstraction from Cymenes

Albini, A.,Sulpizio, A.

, p. 2147 - 2152 (2007/10/02)

The three isomeric cymenes are examined in photochemical reactions involving hydrogen transfer with 1,4-naphthalenedicarbonitrile (NDN), α,α,α-trifluoroacetophenone (TFA), and benzophenone (BP).Selectivity for attack at primary vs tertiary position (P/T) and quantum yield are determined.The reactions are rationalized as involving loose perpendicular complexes yielding a low P/T ratio in the products (with BP n? triplet), a face-to-face charge transfer complex yielding a high P/T (with TFA ??* triplet and also NDN singlet, but only as far as the benzylnaphthalenes 1 and 2 are concerned), and a tighter charge transfer complex yielding again a low P/T in the formation of dibenzomethanocyclooctenes 3, the main products from NDN.The energetic limit of such a directing effect of the conformation of the intermediate complex onto photochemical reactivity is evidenced by the different results obtained with o-cymene.
