1092101-21-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1092101-21-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,9,2,1,0 and 1 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1092101-21:
(9*1)+(8*0)+(7*9)+(6*2)+(5*1)+(4*0)+(3*1)+(2*2)+(1*1)=97
97 % 10 = 7
So 1092101-21-7 is a valid CAS Registry Number.

Synthesis of 6,7,8-trisubstituted purines via a copper-catalyzed amidation reaction
Ibrahim, Nada,Legraverend, Michel
, p. 463 - 465 (2009)
(Chemical Equation Presented) We report herein an efficient method for the synthesis of 6,7,8-trisubstituted purines via a copper-catalyzed amidation reaction from easily accessible starting materials. Furthermore, the resulting 6-benzylsulfanyl-substitut
