1217038-29-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1217038-29-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,7,0,3 and 8 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1217038-29:
(9*1)+(8*2)+(7*1)+(6*7)+(5*0)+(4*3)+(3*8)+(2*2)+(1*9)=123
123 % 10 = 3
So 1217038-29-3 is a valid CAS Registry Number.

Total synthesis of a diarylheptanoid, rhoiptelol B
Reddy, Chada Raji,Rao, Nagavaram Narsimha,Srikanth, Boinapally
experimental part, p. 345 - 351 (2010/05/18)
A stereoselective total synthesis of rhoiptelol B has been accomplished for the first time. The four asymmetric centers were efficiently generated through Keck allylation, Jacobson epoxidation Aldol reaction and reductive etherification as the key steps.
