91471-20-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91471-20-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,4,7 and 1 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 91471-20:
(7*9)+(6*1)+(5*4)+(4*7)+(3*1)+(2*2)+(1*0)=124
124 % 10 = 4
So 91471-20-4 is a valid CAS Registry Number.

Synthesis of Regio- and Stereospecifically Deuterium Labelled 2-Benzylindanes
Kuck, Dietmar
, p. 369 - 374 (2007/10/02)
2-Benzylindenes (1, 1a) are hydrogenated to 2-benzylindanes (2) using tris-(triphenylphosphine)-rhodium(I)-chloride in benzene by a strict cis-1,2 addition of hydrogen to the double bond.Thus, stereo- and regio-specific deuterium labelling at the five-mem
