91860-81-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91860-81-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,8,6 and 0 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 91860-81:
(7*9)+(6*1)+(5*8)+(4*6)+(3*0)+(2*8)+(1*1)=150
150 % 10 = 0
So 91860-81-0 is a valid CAS Registry Number.

Catalysis by lithium perchlorate in dichloromethane: Diels-Alder reactions and 1,3-Claisen rearrangements
Reetz,Gansauer
, p. 6025 - 6030 (1993)
Lithium perchlorate suspended in dichloromethane is an efficient catalyst (4-25 mol-%) for stereoselective Diels-Alder, hetero-Diels-Alder and regioselective 1,3-Claisen rearrangements; this process is milder, safer and environmentally less precarious tha
