133906-89-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133906-89-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,9,0 and 6 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 133906-89:
(8*1)+(7*3)+(6*3)+(5*9)+(4*0)+(3*6)+(2*8)+(1*9)=135
135 % 10 = 5
So 133906-89-5 is a valid CAS Registry Number.

, p. 2145 - 2154 (2007/10/02)
The stereoisomers of (+)-hydantocidin were synthesized by diastereoselective dihydroxylation directly or epoxidation followed by ring opening of 1-oxa-6,8-diazaspirononane-3-ene-7,9-dione systems.
