138663-02-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138663-02-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,6,6 and 3 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 138663-02:
(8*1)+(7*3)+(6*8)+(5*6)+(4*6)+(3*3)+(2*0)+(1*2)=142
142 % 10 = 2
So 138663-02-2 is a valid CAS Registry Number.

The derivatives 1c - 1f were prepared from tetramethyl-(+)-catechin (1b).Their radical reduction with tri-n-butyltin hydride or tris(trimethylsilyl)silane in the presence of azobis(isobutyronitrile) as initiator led to (2R)-(-)-3',4',5,7-tetramethoxyflava
