164365-91-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 164365-91-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,4,3,6 and 5 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 164365-91:
(8*1)+(7*6)+(6*4)+(5*3)+(4*6)+(3*5)+(2*9)+(1*1)=147
147 % 10 = 7
So 164365-91-7 is a valid CAS Registry Number.

The chiral total synthesis of (-)-oncinotine
Ina,Ito,Kibayashi
, p. 1015 - 1016 (1995)
The first chiral synthesis of (-)-oncinotine 1 in natural form has been achieved starting from the protected (S)-N-benzyloxycarbonyl-2-piperidylacetaldehyde 3 based on a new route involving 17-membered ring formation via iminium cyclization, which establi
