176515-30-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 176515-30-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,6,5,1 and 5 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 176515-30:
(8*1)+(7*7)+(6*6)+(5*5)+(4*1)+(3*5)+(2*3)+(1*0)=143
143 % 10 = 3
So 176515-30-3 is a valid CAS Registry Number.

Regiochemistry in Stille couplings of 2,6-dihalopurines
Langli, Geir,Gundersen, Lise-Lotte,Rise, Frode
, p. 5625 - 5638 (2007/10/03)
The regiochemistry in Stille couplings of 2,6-dihalopurines have been studied. 2,6-Dichloropurines react selectively in the 6-position, and 6-chloro-2-iodopurines and 2-bromo-6-chloropurines in the 2-position.
