Check Digit Verification of cas no

The CAS Registry Mumber 1456629-35-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,5,6,6,2 and 9 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1456629-35:
(9*1)+(8*4)+(7*5)+(6*6)+(5*6)+(4*2)+(3*9)+(2*3)+(1*5)=188
188 % 10 = 8
So 1456629-35-8 is a valid CAS Registry Number.

Synthesis of 2-substituted 9,10-anthraquinones

Chang, Meng-Yang,Tai, Hang-Yi

supporting information, p. 3363 - 3372 (2013/10/01)

A convenient preparation of racemic 2-substituted 9,10-anthraquinones that included 2-triazoylethyl skeleton 1 and 2-alkylethyl skeleton 6 is reported. The products were obtained in good yields by a three-or four-step synthetic route based on a sequence of N-bromosuccinimide (NBS)-mediated bromination of 2-ethyl-9,10-anthraquinone 2, nucleophilic substitution, and CuI-catalyzed 1,3-dipolar cycloaddition or alkylation/reductive desulfonylation.
