130253-47-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 130253-47-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,2,5 and 3 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 130253-47:
(8*1)+(7*3)+(6*0)+(5*2)+(4*5)+(3*3)+(2*4)+(1*7)=83
83 % 10 = 3
So 130253-47-3 is a valid CAS Registry Number.

Asymmetric total synthesis of alkaloids and seco-iridoids
Brown, Richard T.,Ford, Mark J.
, p. 2033 - 2036 (2007/10/02)
A chiral cyclopentenolone from Michael addition of an oxazepine derived from ephedrine to a cyclopentene-1,2-dione has been converted into pure enantiomers of established synthetic precursors to alkaloids and seco-iridoids via a novel exchange which recov
