81520-04-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 81520-04-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,5,2 and 0 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 81520-04:
(7*8)+(6*1)+(5*5)+(4*2)+(3*0)+(2*0)+(1*4)=99
99 % 10 = 9
So 81520-04-9 is a valid CAS Registry Number.

NEW ALLYLSTANNANES FOR THE CONNECTIVE CONSTRUCTION OF MONOPROTECTED VICINAL DIOLS

Keck, Gary E.,Abbott, Duain E.,Wiley, Michael R.

, p. 139 - 142 (2007/10/02)

The preparation of allylstannanes 1a-c, all of which bear an oxygen substituent at the allylic terminus, is desribed.These reagents react with alpha- and beta-alkoxyaldehydes in the presence of MgBr2 as Lewis acid to give SE' products with diastereofacial selectivity consistent with "chelation control"; a syn disposition of substituents about the newly formed bond is highly favored in all cases.
