Check Digit Verification of cas no

The CAS Registry Mumber 582300-82-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,8,2,3,0 and 0 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 582300-82:
(8*5)+(7*8)+(6*2)+(5*3)+(4*0)+(3*0)+(2*8)+(1*2)=141
141 % 10 = 1
So 582300-82-1 is a valid CAS Registry Number.

Synthesis of functionalised derivatives of pentaerythritol

Ashry, E. S. H. El,Kilany, Y. El,Hamid, H. Abdel,El-Zemity, S. R.,Boghdady, S.

, p. 111 - 128 (2007/10/03)

Ring opening of the dibenzylidene derivative of pentaerythritol 12 with N-bromosuccinimide gave di-O-benzoyldibromodideoxypentaerythritol (29). Reaction of 20 and 21 with hydrogen bromide in acetic acid afforded di-O-acetyl-di-O-p-toluenesulfonyl pentaerythritol (26). Nucleophilic displacement of the tosyloxy groups in 20 by 1,2,4 triazole afforded 2-phenyl-5-(p-toluenesulfonyloxymethyl)-5-(1,2,4-triazolylmethyl)-1,3-dioxan (31) and 2-phenyl-5,5-bis(1,2,4-triazolylmethyl)-1,3-dioxan (32), and with benzotriazole gave 2-phenyl-5,5-bis(benzotriazolylmethyl)-1,3-dioxan (30). The activity of various derivatives against hepatitis B virus has been studied.
