135042-87-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 135042-87-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,0,4 and 2 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 135042-87:
(8*1)+(7*3)+(6*5)+(5*0)+(4*4)+(3*2)+(2*8)+(1*7)=104
104 % 10 = 4
So 135042-87-4 is a valid CAS Registry Number.

New Ligands Double the Scope of the Catalytic Asymmetric Dihydroxylation of Olefins
Sharpless, K. Barry,Amberg, Willi,Beller, Matthias,Chen, Hou,Hartung, Jens,et al.
, p. 4585 - 4588 (1991)
Improved ligands render terminal olefins good substrates for the osmium-catalyzed asymmetric dihydroxylation (ADH) process, and the amounts of chiral ligand and osmium catalyst required diminish dramatically.
