Check Digit Verification of cas no

The CAS Registry Mumber 1233938-63-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,3,9,3 and 8 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1233938-63:
(9*1)+(8*2)+(7*3)+(6*3)+(5*9)+(4*3)+(3*8)+(2*6)+(1*3)=160
160 % 10 = 0
So 1233938-63-0 is a valid CAS Registry Number.

Remarkably variable reaction modes of frustrated Lewis pairs with non-conjugated terminal diacetylenes

Chen, Chao,Froehlich, Roland,Kehr, Gerald,Erker, Gerhard

supporting information; experimental part, p. 3580 - 3582 (2010/08/07)

The frustrated Lewis pair P(o-tolyl)3/B(C6F 5)3 reacts with 1,7-octadiyne by acetylene C-C coupling to yield the zwitterionic product 2a. In contrast, the P(o-tolyl) 3/B(C6F5)3 Lewis pair reacts with 1,6-heptadiyne by a sequence involving 1,1-carboboration of a terminal acetylene to eventually yield the heterocyclic product 4.
