199851-13-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 199851-13-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,9,8,5 and 1 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 199851-13:
(8*1)+(7*9)+(6*9)+(5*8)+(4*5)+(3*1)+(2*1)+(1*3)=193
193 % 10 = 3
So 199851-13-3 is a valid CAS Registry Number.

An approach to the narciclasine alkaloids via a quinone methide initiated cyclization reaction
Angle, Steven R.,Wada, Tetsuo
, p. 7955 - 7958 (2007/10/03)
The stereoselective synthesis of a possible intermediate for the synthesis of the narciclasine alkaloids from D-glucose is described. The key step of the sequence is a quinone methide initiated cyclization reaction.
