132948-16-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 132948-16-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,9,4 and 8 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 132948-16:
(8*1)+(7*3)+(6*2)+(5*9)+(4*4)+(3*8)+(2*1)+(1*6)=134
134 % 10 = 4
So 132948-16-4 is a valid CAS Registry Number.

Transfer technology III: The synthesis of bridged cyclic polyenes using a new retrosynthetic algorithm as a guide
Warrener,Wang,Weerasuria,Russell
, p. 7069 - 7072 (2007/10/02)
This route to bridged [4] and [8] annulenes employs a new retrosynthetic algorithm, transannular π-bond pairing, as its basis and improved transfer reagents for substituted cyclobutadienes to achieve the synthesis.
