178357-78-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 178357-78-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,8,3,5 and 7 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 178357-78:
(8*1)+(7*7)+(6*8)+(5*3)+(4*5)+(3*7)+(2*7)+(1*8)=183
183 % 10 = 3
So 178357-78-3 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.
