Check Digit Verification of cas no
The CAS Registry Mumber 25662-28-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,6,6 and 2 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 25662-28:
(7*2)+(6*5)+(5*6)+(4*6)+(3*2)+(2*2)+(1*8)=116
116 % 10 = 6
So 25662-28-6 is a valid CAS Registry Number.

Oxidative carbomethoxylation of alkenes using a Pd(II)/molybdovanadophosphate (NPMoV) system under carbon monoxide and air
Yokota, Takahiro,Sakaguchi, Satoshi,Ishii, Yasutaka
, p. 5005 - 5008 (2007/10/03)
Oxidative carbomethoxylation of cyclopentene (1) under carbon monoxide and air by the use of a catalytic amount of Pd(OAc)2 and molybdovanadophosphate (NPMoV) led to dimethyl cis-1,2-cyclopentanedicarboxylate (2) and dimethyl cis-1,3-cyclopentanedicarboxylate (3) in good yields. Total yields of 2 and 3 were found to be improved by adding a small amount of NH4Cl. Several alkenes were similarly converted into the corresponding dimethyl dicarboxylates. The role of Cl- in the present catalytic system is suggested.
