1499187-53-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1499187-53-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,9,9,1,8 and 7 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1499187-53:
(9*1)+(8*4)+(7*9)+(6*9)+(5*1)+(4*8)+(3*7)+(2*5)+(1*3)=229
229 % 10 = 9
So 1499187-53-9 is a valid CAS Registry Number.

Desymmetrization of cyclic olefins via asymmetric Heck reaction and hydroarylation
Liu, Sijia,Zhou, Jianrong
, p. 11758 - 11760 (2013/12/04)
An asymmetric Heck reaction allows desymmetrization of substituted cyclic olefins in high dr and ee. A bisphosphine oxide is uniquely stereoselective for this purpose. Desymmetrization of bicyclic olefins via hydroarylation can also be realized in high ee.
