82511-16-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 82511-16-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,5,1 and 1 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 82511-16:
(7*8)+(6*2)+(5*5)+(4*1)+(3*1)+(2*1)+(1*6)=108
108 % 10 = 8
So 82511-16-8 is a valid CAS Registry Number.

Alkynylquinones. Synthesis of 2-Alkynyl-5-methoxy-1,4-benzoquinones
West, Kevin F.,Moore, Harold W.
, p. 3591 - 3593 (1982)
An experimentally simple and efficient synthesis of 2-alkynyl-5-methoxy-1,4-benzoquinones is described.This involves the 1,2-addition of lithium acetylides to 4,5-dimethoxy-1,2-benzoquinone to give the quinols 2a-i.Hydrolysis of these adducts with dilute
