164359-99-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 164359-99-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,4,3,5 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 164359-99:
(8*1)+(7*6)+(6*4)+(5*3)+(4*5)+(3*9)+(2*9)+(1*9)=163
163 % 10 = 3
So 164359-99-3 is a valid CAS Registry Number.

Regioselective Pd-mediated coupling between 2,6-dichloropurines and organometallic reagents
Gundersen, Lise-Lotte,Langli, Geir,Rise, Frode
, p. 1945 - 1948 (1995)
Selective coupling in the purine 6-position has been achieved, by reacting N-benzylated 2,6-dichloropurines with organotin and organozinc reagents. The positional identity of the products were established from long range HETCOR or nOe NMR experiments.
