Check Digit Verification of cas no

The CAS Registry Mumber 1183943-91-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,3,9,4 and 3 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1183943-91:
(9*1)+(8*1)+(7*8)+(6*3)+(5*9)+(4*4)+(3*3)+(2*9)+(1*1)=180
180 % 10 = 0
So 1183943-91-0 is a valid CAS Registry Number.

Vanadium-catalyzed oxidative Strecker reaction: α-C-H cyanation of para-methoxyphenyl (PMP)-protected primary amines

Chen, Chuo,Zhu, Chen,Xia, Ji-Bao

supporting information, p. 232 - 234 (2014/01/06)

We describe an oxidative Strecker reaction that allows for direct cyanation of para-methoxyphenyl (PMP)-protected primary amines. A vanadium(V) complex was used as the catalyst and TBHP as the oxidant. The cyanation occurs at the α-C position bearing either an alkyl or an aromatic group. This method provides a direct access to α-aminonitrile from amines with one-carbon extension.
