Check Digit Verification of cas no

The CAS Registry Mumber 27872-69-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,8,7 and 2 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 27872-69:
(7*2)+(6*7)+(5*8)+(4*7)+(3*2)+(2*6)+(1*9)=151
151 % 10 = 1
So 27872-69-1 is a valid CAS Registry Number.

NUCLEOPHILIC SUBSTITUTION OF α-HALO KETONES. XXI. STRUCTURE-REACTIVITY RELATIONSHIPS IN THE ACETOLYSIS OF 3-SUBSTITUTED 1-CHLORO-3-PHENYLTHIO-2-PROPANONES

Pusino, Alba,Rosnati, Vittorio,Saba, Antonio,Franco, Andrea

, p. 475 - 482 (2007/10/02)

The acetolyses of α-chloro ketones 1a-d have been re-investigated under standard conditions and compared with those of the corresponding isomeric substrates 2a-d.It has been shown that participation by the neighbouring phenylthio group, involving a 1-3 shift of the latter, does occur in part even in the case of 1d, while it is the only process in the case of 1e.A few structure-reactivity relationships in the two series of substrates are discussed.
