Check Digit Verification of cas no

The CAS Registry Mumber 1229931-83-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,9,9,3 and 1 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1229931-83:
(9*1)+(8*2)+(7*2)+(6*9)+(5*9)+(4*3)+(3*1)+(2*8)+(1*3)=172
172 % 10 = 2
So 1229931-83-2 is a valid CAS Registry Number.

Iodine-promoted domino reaction leading to N -substituted 2-aminoquinoline-3-carbonitriles under microwave irradiation

Jiang, Bo,Li, Chao,Tu, Shu-Jiang,Shi, Feng

experimental part, p. 482 - 487 (2010/08/19)

A new iodine-promoted domino reaction of 2-aminochromene-3-carbonitriles with various isocyanates is described, and a set of polyfunctionalized N-substituted 2-aminoquinoline-3-carbonitriles with high regioselectivity were successfully synthesized under microwave heating. In this reaction, the ring-opening/recyclization process occurs unexpectedly at the ring of 4H-pyran with different isocyanates.
