214477-03-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 214477-03-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,4,4,7 and 7 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 214477-03:
(8*2)+(7*1)+(6*4)+(5*4)+(4*7)+(3*7)+(2*0)+(1*3)=119
119 % 10 = 9
So 214477-03-9 is a valid CAS Registry Number.

New and efficient selenium reagents for stereoselective selenenylation reactions
Fragale, Gianfranco,Neuburger, Markus,Wirth, Thomas
, p. 1867 - 1868 (1998)
The simple substitution of an aryl proton by a methoxy substituent improves the selectivity of the stereoselective selenenylation reaction dramatically, leading to addition products with diastereomeric ratios up to 50:1 in the methoxyselenenylation reacti
