129006-40-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129006-40-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,0,0 and 6 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 129006-40:
(8*1)+(7*2)+(6*9)+(5*0)+(4*0)+(3*6)+(2*4)+(1*0)=102
102 % 10 = 2
So 129006-40-2 is a valid CAS Registry Number.

PURINES. IX. REACTION OF 9-PHENYL-9H-PURINE-2-CARBONITRILES WITH GRIGNARD REAGENTS
Tanji, Ken-ichi,Higashino, Takeo
, p. 435 - 440 (2007/10/02)
The palladium-catalyzed cross-coupling reaction of 2- and 6-chloro-9-phenyl-9H-purines with potassium cyanide proceeded to give 9-phenyl-9H-purine-2- (3a-c) and -6-carbonitriles (4a-c).The conversion of the cyano group at the 2-position into the correspon
