131509-72-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131509-72-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,5,0 and 9 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 131509-72:
(8*1)+(7*3)+(6*1)+(5*5)+(4*0)+(3*9)+(2*7)+(1*2)=103
103 % 10 = 3
So 131509-72-3 is a valid CAS Registry Number.

Reactions of β-Pinene with Aromatic Aldehydes
Majewski, Marek,Bantle, Gary W.
, p. 2549 - 2558 (2007/10/02)
Aromatic aldehydes add to β-pinene under Lewis acid catalyzed Prins reaction conditions and yield the corresponding homoallylic alcohols.The reactions proceed in poor yield when electron donating substituents are present on the aromatic ring.
