87746-87-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87746-87-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,7,4 and 6 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 87746-87:
(7*8)+(6*7)+(5*7)+(4*4)+(3*6)+(2*8)+(1*7)=190
190 % 10 = 0
So 87746-87-0 is a valid CAS Registry Number.

Rhodium catalysed carbonylation of homoallylic alcohols to spiropyrans bearing quaternary centres
Kitsos-Rzychon, Beate,Eilbracht, Peter
, p. 10721 - 10732 (2007/10/03)
A convenient preparation of substituted-spiropyrans via rhodium catalysed hydroformylation of homoallylic alcohols, followed by a condensation sequence to form hemiacetals and 2,2,3,3-tetraalkyl-4[H]- pyrans, is described.
