156540-58-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 156540-58-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,5,4 and 0 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 156540-58:
(8*1)+(7*5)+(6*6)+(5*5)+(4*4)+(3*0)+(2*5)+(1*8)=138
138 % 10 = 8
So 156540-58-8 is a valid CAS Registry Number.

Diastereoselectivity in the osmium-catalyzed dihydroxylation of allylic amides and carbamates
Krysan,Rockway,Haight
, p. 625 - 632 (2007/10/02)
The stereochemistry of the osmium-catalyzed dihydroxylation of a series of chiral allylic amides and carbamates has been studied. The diastereoselectivity of these reactions was found to be dependent upon the solvent and the nitrogen protecting group as w
