Check Digit Verification of cas no

The CAS Registry Mumber 98238-00-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,2,3 and 8 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 98238-00:
(7*9)+(6*8)+(5*2)+(4*3)+(3*8)+(2*0)+(1*0)=157
157 % 10 = 7
So 98238-00-7 is a valid CAS Registry Number.

Total Synthesis of (-)-Crinine. Use of Tandem Cationic Aza-Cope Rearrangement/Mannich Cyclizations for the Synthesis of Enantiomerically Pure Amaryllidaceae Alkaloids

Overman, Larry E.,Sugai, Soji

, p. 745 - 749 (2007/10/02)

The total synthesis of enantiomerically pure (-)-crinine (1) in 10 steps and 6percent overall yield from cyclopentene oxide is reported.The key step was the rearrangement of 7 upon reaction with AgNO3 at 25 deg C to give cis-perhydroindolone 8 in 81 perce
