Check Digit Verification of cas no
The CAS Registry Mumber 345948-31-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,5,9,4 and 8 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 345948-31:
(8*3)+(7*4)+(6*5)+(5*9)+(4*4)+(3*8)+(2*3)+(1*1)=174
174 % 10 = 4
So 345948-31-4 is a valid CAS Registry Number.

ADDITION OF AMINE NUCLEOPHILES TO DIPHOSPHORYLALKYNES. THE CHEMISTRY OF THE DERIVED ENAMINES
Whitesell, Marilyn A.,Kyba, Evan P.
, p. 1679 - 1682 (2007/10/02)
Amine nucleophiles bearing at least one hydrogen substituent add across tetraethyl ethynyldiphosphonate to give enamine derivatives, one of which (derived from cyclohexylamine) has been evaluated as an imine anion precursor in alkylations and Wittig-Horne
