118807-58-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 118807-58-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,8,0 and 7 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 118807-58:
(8*1)+(7*1)+(6*8)+(5*8)+(4*0)+(3*7)+(2*5)+(1*8)=142
142 % 10 = 2
So 118807-58-2 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
