73664-30-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 73664-30-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,6,6 and 4 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 73664-30:
(7*7)+(6*3)+(5*6)+(4*6)+(3*4)+(2*3)+(1*0)=139
139 % 10 = 9
So 73664-30-9 is a valid CAS Registry Number.

supporting information; experimental part, p. 2659 - 2662 (2009/10/02)
The first examples of Rh-catalyzed cyclohydrocarbonylation-bicyclization of N-allylic amides of arylacetic acids are reported. This novel carbonylative bicyclization process was successfully applied to the rapid syntheses of crispine A and its analogues (
