Check Digit Verification of cas no

The CAS Registry Mumber 156725-12-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,7,2 and 5 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 156725-12:
(8*1)+(7*5)+(6*6)+(5*7)+(4*2)+(3*5)+(2*1)+(1*2)=141
141 % 10 = 1
So 156725-12-1 is a valid CAS Registry Number.

Cycloaddition of Nitrile Oxides to Homochiral Vinyl Ethers

Boa, Andrew N.,Dawkins, David A.,Hergueta, Antonio R.,Jenkins, Paul R.

, p. 953 - 960 (2007/10/02)

In the cycloaddition of a range of nitrile oxides with homochiral vinyl ethers the diastereoselectivity observed is dependent on the chiral auxiliary used.A brief comparison is made with the diastereoselectivity of the corresponding nitrosoalkene cycloaddition, and also to the nitrile oxide cycloaddition to chiral acrylic acid esters bearing the most successful auxiliaries from the vinyl ether study.
