74568-88-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74568-88-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,5,6 and 8 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 74568-88:
(7*7)+(6*4)+(5*5)+(4*6)+(3*8)+(2*8)+(1*8)=170
170 % 10 = 0
So 74568-88-0 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
