129744-49-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129744-49-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,7,4 and 4 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 129744-49:
(8*1)+(7*2)+(6*9)+(5*7)+(4*4)+(3*4)+(2*4)+(1*9)=156
156 % 10 = 6
So 129744-49-6 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.
