802903-28-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 802903-28-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,0,2,9,0 and 3 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 802903-28:
(8*8)+(7*0)+(6*2)+(5*9)+(4*0)+(3*3)+(2*2)+(1*8)=142
142 % 10 = 2
So 802903-28-2 is a valid CAS Registry Number.

Enantioselective construction of carbobicyclic scaffolds
Taber, Douglass F.,He, Yigang,Xu, Ming
, p. 13900 - 13901 (2007/10/03)
Allylic and benzylic Grignard reagents smoothly open phenylalkynyl-activated cyclic trisubstituted epoxides at the more substituted carbon atom to give secondary alcohols with a chiral quaternary center. These alcohols are good substrates for the construc
