74164-84-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74164-84-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,1,6 and 4 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 74164-84:
(7*7)+(6*4)+(5*1)+(4*6)+(3*4)+(2*8)+(1*4)=134
134 % 10 = 4
So 74164-84-4 is a valid CAS Registry Number.

An enantiocontrolled synthesis of pyrrolizidines, (-)-platynecine and (-)-hadinecine
Kang, Sung Ho,Kim, Geun Tae,Yoo, Yong Sang
, p. 603 - 606 (2007/10/03)
Trisubstituted allylic alcohols 13 and 14 have been converted into a single isomeric trans-oxazoline 16 via an intramolecular iodoamidation of the corresponding trichloroacetimidates, which have been elaborated into (-)-platynecine 1 and(-)-hadinecine 2 via a common intermediate pyrrolizidine.
