Check Digit Verification of cas no

The CAS Registry Mumber 802590-15-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,0,2,5,9 and 0 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 802590-15:
(8*8)+(7*0)+(6*2)+(5*5)+(4*9)+(3*0)+(2*1)+(1*5)=144
144 % 10 = 4
So 802590-15-4 is a valid CAS Registry Number.

Yu, Yan-Bo,Chen, Hong-Liang,Wang, Li-Yi,Chen, Xin-Zheng,Fu, Bin

scheme or table, p. 4858 - 4865 (2010/04/05)

Structurally diverse thiazoles with electron-donating and electron-withdrawing groups were conveniently synthesized through manganese dioxide (MnO2) oxidation of the corresponding thiazolines. The effect of substitution at the 2- and 4-positions was investigated. The desired thiazoles with aryl or vinyl substitutions at the 2- or 4-position can be obtained in good to excellent yields.
