Check Digit Verification of cas no
The CAS Registry Mumber 502614-04-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,2,6,1 and 4 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 502614-04:
(8*5)+(7*0)+(6*2)+(5*6)+(4*1)+(3*4)+(2*0)+(1*4)=102
102 % 10 = 2
So 502614-04-2 is a valid CAS Registry Number.

Indole-Diterpene Synthetic Studies: Total Synthesis of (-)-21-Isopentenylpaxilline
Smith III, Amos B.,Cui, Haifeng
, p. 3908 - 3938 (2007/10/03)
An efficient, stereocontrolled total synthesis of the complex indole-diterpene alkaloid (-)-21-isopentenylpaxilline (1) has been achieved. Key elements of the synthesis include the stereocontrolled construction of the advanced eastern hemisphere (-)-68, i
