263390-02-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 263390-02-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,3,3,9 and 0 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 263390-02:
(8*2)+(7*6)+(6*3)+(5*3)+(4*9)+(3*0)+(2*0)+(1*2)=129
129 % 10 = 9
So 263390-02-9 is a valid CAS Registry Number.

A highly efficient method for the synthesis of guanidinium derivatives
Manimala, Joseph C,Anslyn, Eric V
, p. 565 - 567 (2007/10/03)
A high yielding synthesis of guanidiniums with the use of the ethyl carbamate protecting group is presented. This strategy eliminates many steric hindrance and electronic problems. The deprotection of the products by Me3SiBr is also demonstrated.
