Check Digit Verification of cas no

The CAS Registry Mumber 69773-58-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,7,7 and 3 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 69773-58:
(7*6)+(6*9)+(5*7)+(4*7)+(3*3)+(2*5)+(1*8)=186
186 % 10 = 6
So 69773-58-6 is a valid CAS Registry Number.

Synthesis of N,N-dimethyl-2-(tributylstannyl)methyl-5-substituted benzylamines as a quinodimethane precursor by the reaction of N,N-dimethyl- N-(tributylstannyl)methyl-4-substituted benzylammonium salts with lithium diisopropylamide

Maeda, Yasuhiro,Sato, Yoshiro

, p. 508 - 511 (2007/10/03)

Reaction of N,N-dimethyl-N-(tributylstannyl)methyl-4-substituted benzylammonium salts 2 with lithium diisopropylamide (LDA) gave N,N-dimethyl- 2-(tributylstannyl)methyl-5-substituted benzylamines 3 as the main products. Treatment of 3 with iodomethane followed by tetrabutylammonium fluoride (TBAF) in the presence of dimethyl fumarate gave the corresponding dimethyl trans-1,2,3,4-tetrahydro-6-substituted naphthalene-2,3-dicarboxylates 15 in good yields.
