1620093-22-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1620093-22-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,0,0,9 and 3 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1620093-22:
(9*1)+(8*6)+(7*2)+(6*0)+(5*0)+(4*9)+(3*3)+(2*2)+(1*2)=122
122 % 10 = 2
So 1620093-22-2 is a valid CAS Registry Number.

Efficient asymmetric synthesis of spiro-2(3H)-furanones via phase-transfer-catalyzed alkynylation
Wu, Xiangfei,Shirakawa, Seiji,Maruoka, Keiji
, p. 5388 - 5392 (2014)
Efficient asymmetric synthesis of spiro-2(3H)-furanones was achieved via phase-transfer-catalyzed highly enantioselective alkynylation of cyclic β-keto esters with hypervalent iodine reagents. This journal is the Partner Organisations 2014.
