Check Digit Verification of cas no

The CAS Registry Mumber 87025-18-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,0,2 and 5 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 87025-18:
(7*8)+(6*7)+(5*0)+(4*2)+(3*5)+(2*1)+(1*8)=131
131 % 10 = 1
So 87025-18-1 is a valid CAS Registry Number.

The regiospecific phase transfer catalyzed reductive carbonylation of azadienes

Alper, Howard,Amaratunga, Shiyamalie

, p. 1309 - 1313 (2007/10/02)

Reaction of an azadiene with cobalt carbonyl, carbon monoxide, and methyl iodide under phase transfer catalysis conditions (benzene, water or aqueous NaOH, benzyltriethylammonium chloride) affords allylic amides in reasonable yields.This regiospecific reaction is sensitive to the concentration of base.One can also effect this transformation using acidic catalysis.A mechanism is proposed for the reductive carbonylation reaction.
