921763-75-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 921763-75-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,1,7,6 and 3 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 921763-75:
(8*9)+(7*2)+(6*1)+(5*7)+(4*6)+(3*3)+(2*7)+(1*5)=179
179 % 10 = 9
So 921763-75-9 is a valid CAS Registry Number.

Total synthesis of amphidinolide E
Va, Porino,Roush, William R.
, p. 15960 - 15961 (2007/10/03)
A convergent and highly stereocontrolled synthesis of amphidinolide E (1) has been accomplished. The synthesis features a highly diastereoselective (>20:1) BF3·Et2O promoted [3+2] annulation reaction between aldehyde 3 and allylsilan
