Check Digit Verification of cas no

The CAS Registry Mumber 19735-67-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,7,3 and 5 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 19735-67:
(7*1)+(6*9)+(5*7)+(4*3)+(3*5)+(2*6)+(1*7)=142
142 % 10 = 2
So 19735-67-2 is a valid CAS Registry Number.

Compatibility of Various Carbanion Nucleophiles with Heteroaromatic Nucleophilic Substitution by the SRN1 Mechanism

Wong, Jim-Wah,Natalie Jr., Kenneth J.,Nwokogu, Godson C.,Pisipati, Jyothi S.,Flaherty, Patrick T.,Greenwood, Thomas D.,Wolfe, James F.

, p. 6152 - 6159 (2007/10/03)

Carbanions generated from 2,4,4-trimethyl-2-oxazoline (1a), 2-benzyl-4,4-dimethyl-2-oxazoline (1b), 2,4-dimethylthiazole (13a), 2-benzyl-4-methylthiazole (13b), N,N-dimethylacetamide (17a), tert-butyl acetate (17b), ethyl phenylacetate (17c), N-methyl-N-phenyl-2-butenamide (22), tert-butyl 3-butenoate (25), and dimethyl methylphosphonate (29a) by means of KNH2 in liquid NH3 all reacted with 2-bromopyridine (2) via photoassisted reactions that exhibited characteristics of the SRN1 mechanism. Similar results were obtained in reactions of these carbanions with other substrates, including 2-chloroquinoline (6), iodobenzene (9), bromobenzene (10), and bromomesitylene (11).
