142746-84-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142746-84-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,7,4 and 6 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 142746-84:
(8*1)+(7*4)+(6*2)+(5*7)+(4*4)+(3*6)+(2*8)+(1*4)=137
137 % 10 = 7
So 142746-84-7 is a valid CAS Registry Number.

Highly Selective High-Pressure Cycloadditions
Winterfeldt, Ekkehard,Wray, Victor
, p. 2159 - 2162 (2007/10/02)
High-pressure cycloadditions of the nonsymmetric dienophiles itaconic anhydride (6) and citraconic anhydride (7) to the homochiral cyclopentadiene 1 can be exercised with excellent regioselctivity (100percent) and face selectivity. Key Words: High-pressur
