Check Digit Verification of cas no
The CAS Registry Mumber 169219-68-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,9,2,1 and 9 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 169219-68:
(8*1)+(7*6)+(6*9)+(5*2)+(4*1)+(3*9)+(2*6)+(1*8)=165
165 % 10 = 5
So 169219-68-5 is a valid CAS Registry Number.

Synthesis of exo- and endo-6,7-epoxytropanes
Justice, David E.,Malpass, John R.
, p. 11963 - 11976 (2007/10/03)
Diastereoisomeric N-protected 2,3-epoxy-4-amino-cycloheptanols are synthesised; cyclisation of derivatives provides a practical route to N-protected exo-(β)-6,7-epoxynortropanes and the first endo-(α-)-6,7-epoxynortropane. Hydride reduction gives the corr
