178208-17-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 178208-17-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,8,2,0 and 8 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 178208-17:
(8*1)+(7*7)+(6*8)+(5*2)+(4*0)+(3*8)+(2*1)+(1*7)=148
148 % 10 = 8
So 178208-17-8 is a valid CAS Registry Number.

A novel asymmetric route to the 1,3-disubstituted tetrahydroisoquinoline, (-)-argemonine
Munchhof, Michael J.,Meyers
, p. 4607 - 4610 (2007/10/03)
Chiral bicyclic lactam 13 was converted to the natural product (-)-argemonine 9 in six steps. This novel route to argemonine represents a general strategy for the preparation of chiral 1,3-disubstituted tetrahydroisoquinolines.
