1335000-89-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1335000-89-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,5,0,0 and 0 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1335000-89:
(9*1)+(8*3)+(7*3)+(6*5)+(5*0)+(4*0)+(3*0)+(2*8)+(1*9)=109
109 % 10 = 9
So 1335000-89-9 is a valid CAS Registry Number.

An asymmetric dihydroxylation route to (-)-bulgecinine
Show, Krishanu,Upadhyay, Puspesh K.,Kumar, Pradeep
experimental part, p. 1234 - 1238 (2011/10/19)
The stereoselective synthesis of (-)-bulgecinine is reported from L-aspartic acid using Sharpless asymmetric dihydroxylation and intramolecular cyclization via nucleophilic displacement of a-tosylate as key steps.
