115377-40-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 115377-40-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,5,3,7 and 7 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 115377-40:
(8*1)+(7*1)+(6*5)+(5*3)+(4*7)+(3*7)+(2*4)+(1*0)=117
117 % 10 = 7
So 115377-40-7 is a valid CAS Registry Number.

CONJUGATED CARBODIIMIDES: PREPARATION AND THERMAL CYCLIZATION TO 2-AMINOPYRIDINE DERIVATIVES
Molina, Pedro,Fresneda, Pilar M.,Alarcon, Pascual
, p. 379 - 380 (2007/10/02)
The aza-Wittig reaction of iminophosphorane (2) with isocyanates leads to conjugated carbodiimides which undergo electrocyclic ring-closure to give 2-aminopyridine derivatives.
