311309-53-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 311309-53-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,1,3,0 and 9 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 311309-53:
(8*3)+(7*1)+(6*1)+(5*3)+(4*0)+(3*9)+(2*5)+(1*3)=92
92 % 10 = 2
So 311309-53-2 is a valid CAS Registry Number.

Tandem radical cyclizations with iodoaryl azides: formal total synthesis of (+/-)-aspidospermidine.
Patro,Murphy
, p. 3599 - 3601 (2007/10/03)
An iodoazide radical cascade cyclization strategy has been used as the key step in a formal synthesis of aspidospermidine. Specifically, this step generated the alkaloid's B- and E-rings in the ethylidene-functionalized tetracycle 5. In turn, this was con
