344236-45-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 344236-45-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,4,2,3 and 6 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 344236-45:
(8*3)+(7*4)+(6*4)+(5*2)+(4*3)+(3*6)+(2*4)+(1*5)=129
129 % 10 = 9
So 344236-45-9 is a valid CAS Registry Number.

Synthesis of Symmetrically Substituted Bicyclic Guanidines
Schmidtchen, Franz P.
, p. 2175 - 2182 (2007/10/02)
The symmetrically 2,2,8,8-tetraalkylsubstituted bicyclic guanidines 14a and b are prepared stereoselectively via construction of the open-chain triamines 11a and b and subsequent cyclisation.A one-pot reaction gives the unsubstituted guanidine 14c in high
