860818-44-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 860818-44-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,0,8,1 and 8 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 860818-44:
(8*8)+(7*6)+(6*0)+(5*8)+(4*1)+(3*8)+(2*4)+(1*4)=186
186 % 10 = 6
So 860818-44-6 is a valid CAS Registry Number.

Steps towards a practical synthesis of macrocyclic bisbenzylisoquinolines

Al-Hiari, Yusuf M.,Bennett, Stephen J.,Cox, Brian,Davies, Robert J.,Khalaf, Abedawn I.,Waigh, Roger D.,Worsley, Alan J.

, p. 647 - 659 (2007/10/03)

There are more than 400-reported bisbenzylisoquinoline alkaloids, many with interesting biological activity, but the reported syntheses are long and low yielding. As a result, there have been no systematic attempts at exploitation of the potential therapeutic applications. The concept of a sulfur 'stitch', restricting the conformational freedom of intermediates in the synthesis, will potentially allow analogues of the natural products to be prepared using relatively efficient routes. The synthesis of intermediate sulfur heterocycles is reported, based on 2,8-dimethylphenoxathiin, leading via 2,8-bis(bromomethyl) phenoxathiin-10,10-dioxide to a synthesis of 3,4,8,9-tetrahydro-13-oxa-6-thia-2, 10-diazapentacene, a key potential intermediate on the route to a variety of macrocyclic bisbenzylisoquinolines.
