220025-49-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 220025-49-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,0,2 and 5 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 220025-49:
(8*2)+(7*2)+(6*0)+(5*0)+(4*2)+(3*5)+(2*4)+(1*9)=70
70 % 10 = 0
So 220025-49-0 is a valid CAS Registry Number.

, p. 2441 - 2442 (2007/10/03)
The enantioselective Claisen rearrangement of difluorovinyl allyl ethers was achieved, for the first time, in moderate to good enantioselectivity using a chiral boron reagent as the Lewis acid.
