Check Digit Verification of cas no

The CAS Registry Mumber 70972-96-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,9,7 and 2 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 70972-96:
(7*7)+(6*0)+(5*9)+(4*7)+(3*2)+(2*9)+(1*6)=152
152 % 10 = 2
So 70972-96-2 is a valid CAS Registry Number.

Reactions of N-Halogenobenzylmethylamines with Triethylamine in Acetonitrile. Effect of Leaving Group upon the Imine-forming Transition State

Cho, Bong Rae,Namgoong, Sung Keon,Kim, Tae Rin

, p. 853 - 856 (2007/10/02)

Reactions of N-halogenobenzylmethylamines (1) and (2) with Et3N-MeCN have been investigated kinetically.Eliminations from (1) and (2) were quantitative and regiospecific, producing only benzylidenemethylamines.For the elimination reaction of (1) with Et3N, kH/kD 5.7, ρ 0.88, 9.1 kcal mol-1, and -42.4 cal mol-1 K-1 were determined.The transition-state structure is assessed as being highly symmetric with similar extents of Cβ-H and Nα-Cl bond cleavage, little carbanionic character, and significant ?-bond formation.The structure of the transition state changes only slightly with the change in the leaving group from Cl to Br.
