1093663-32-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1093663-32-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,9,3,6,6 and 3 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1093663-32:
(9*1)+(8*0)+(7*9)+(6*3)+(5*6)+(4*6)+(3*3)+(2*3)+(1*2)=161
161 % 10 = 1
So 1093663-32-1 is a valid CAS Registry Number.

Controlling regiochemistry in the gold-catalyzed synthesis of unsaturated spiroketals
Paioti, Paulo H. S.,Ketcham, John M.,Aponick, Aaron
, p. 5320 - 5323 (2015/01/16)
A novel gold-catalyzed synthesis of unsaturated spiroketals that addresses regioselectivity issues commonly reported in metal-catalyzed spiroketalization of alkynes is reported. The reaction sequence is regulated by an acetonide protecting group which und
