Check Digit Verification of cas no

The CAS Registry Mumber 1616890-19-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,6,8,9 and 0 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1616890-19:
(9*1)+(8*6)+(7*1)+(6*6)+(5*8)+(4*9)+(3*0)+(2*1)+(1*9)=187
187 % 10 = 7
So 1616890-19-7 is a valid CAS Registry Number.

Synthesis of β-cyanopropan-1-one derivates by domino reaction

supporting information, p. 3454 - 3457 (2014/07/08)

Domino nucleophilic addition was used for four-component Al 2O3-catalyzed environmentally friendly synthesis of polysubstituted β-cyanopropan-1-one. Domino nucleophilic addition involves removal of the cyano group linked to active methylene by the action of KF, and direct addition to enones. The reaction's capability for nucleophilic attack is F- > CN- in DMF. The use of low-toxicity reagents hints that the reaction is more environmentally friendly than traditional approaches. This journal is the Partner Organisations 2014.
