1020085-28-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1020085-28-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,0,0,8 and 5 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1020085-28:
(9*1)+(8*0)+(7*2)+(6*0)+(5*0)+(4*8)+(3*5)+(2*2)+(1*8)=82
82 % 10 = 2
So 1020085-28-2 is a valid CAS Registry Number.

Bismuth-triflate-catalyzed Prins-Ritter reaction - An efficient synthesis of 4-amidotetrahydropyrans
Yadav,Subba Reddy,Chaya,Narayana Kumar
, p. 769 - 773 (2008)
Bismuth(III) triflate is found to be an effective Lewis acid in catalyzing a three-component reaction of homoallylic alcohol, carbonyl compound, and nitrile at ambient temperature via the Prins-Ritter sequence to furnish 4-amidotetrahydropyrans in high yi
