875-08-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 875-08-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,7 and 5 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 875-08:
(5*8)+(4*7)+(3*5)+(2*0)+(1*8)=91
91 % 10 = 1
So 875-08-1 is a valid CAS Registry Number.

Cyclobutane Ring Opening of Pin-2(10)-ene with Mercury(II) Salts. A New, High-yield Synthesis of p-Mentha-1,8-dien-7-ol

Bluthe, Norbert,Ecoto, Jules,Fetizon, Marcel,Lazare, Sylvain

, p. 1747 - 1751 (2007/10/02)

The nucleophilic attack of pin-2(10)-ene-mercury(II) complex systems by water results in the opening of the four-membered ring leading to an allylic organomercury(II) derivative (11) with the p-menthane skeleton.This intermediate can be reduced by hydride to p-menth-1(2)-en-8-ol (6a) or can undergo an in situ SE2' elimination yielding p-menth-1(7)-en-8-ol (9a), in high yields. (-)-2,10-Epoxypinane (15) reacts with mercury(II) salts at room temperature, giving the diol (16) in a quantitative yield.Compound (16) is a suitable intermediate for convenient preparation of p-mentha-1,8-dien-7-ol (17) and its derivatives.
