Check Digit Verification of cas no

The CAS Registry Mumber 113308-04-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,3,0 and 8 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 113308-04:
(8*1)+(7*1)+(6*3)+(5*3)+(4*0)+(3*8)+(2*0)+(1*4)=76
76 % 10 = 6
So 113308-04-6 is a valid CAS Registry Number.

FIVE-MEMBERED 2,3-DIOXOHETEROCYCLES 3. THE REACTION OF 5-ARYL-2,3-DIHYDROFURAN-2,3-DIONES WITH ALIPHATIC AND AROMATIC NITRILES

Andreichikov, Yu. S.,Nekrasov, D. D.,Rudenko, M. A.,Konovalov, A. Yu.

, p. 610 - 613 (2007/10/02)

On reaction of 5-aryl-2,3-dihydrofuran-2,3-diones with α-aminoisobutyronitrile, o-aminobenzonitrile, and β-anilinopropionitrile, we obtained aroylpyruvic acid N-(1-methyl-1-cyanoethyl)-, N-(o-cyanophenyl)-, and N-phenyl-N-(cyanoethyl)-amides, respectively.On reaction of 5-aryl-2,3-dihydrofuran-2,3-diones with cyanoacetamide we obtained aroylacetic acid N-(cyanoacetyl)amides, while in the case of methyleneaminoacetonitrile and p-dimethylaminobenzonitrile we obtained (6-aryl-4-oxo-2,3-dihydro-1,3-oxazin-3-yl)acetonitriles and 2-(p-dimethylaminophenyl)-6-aryl-1,3-oxazine-4-ones, respectively.
