1268268-91-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1268268-91-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,8,2,6 and 8 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1268268-91:
(9*1)+(8*2)+(7*6)+(6*8)+(5*2)+(4*6)+(3*8)+(2*9)+(1*1)=192
192 % 10 = 2
So 1268268-91-2 is a valid CAS Registry Number.

Total synthesis of brevenal
Zhang, Yuan,Rohanna, John,Zhou, Jie,Iyer, Karthik,Rainier, Jon D.
, p. 3208 - 3216 (2011/04/25)
This Article describes the total synthesis of the marine ladder toxin brevenal utilizing a convergent synthetic strategy. Critical to the success of this work was the use of olefinic-ester cyclization reactions and the utilization of glycal epoxides as precursors to C-C and C-H bonds.
