Check Digit Verification of cas no

The CAS Registry Mumber 31883-94-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,8,8 and 3 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 31883-94:
(7*3)+(6*1)+(5*8)+(4*8)+(3*3)+(2*9)+(1*4)=130
130 % 10 = 0
So 31883-94-0 is a valid CAS Registry Number.

Acceptor-Controlled Transfer Dehydration of Amides to Nitriles

Okabe, Hiroyuki,Naraoka, Asuka,Isogawa, Takahiro,Oishi, Shunsuke,Naka, Hiroshi

supporting information, p. 4767 - 4770 (2019/06/17)

Palladium-catalyzed dehydration of primary amides to nitriles efficiently proceeds under mild, aqueous conditions via the use of dichloroacetonitrile as a water acceptor. A key to the design of this transfer dehydration catalysis is the identification of an efficient water acceptor, dichloroacetonitrile, that preferentially reacts with amides over other polar functional groups with the aid of the Pd catalyst and makes the desired scheme exergonic, thereby driving the dehydration.
