Check Digit Verification of cas no

The CAS Registry Mumber 1268356-31-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,8,3,5 and 6 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1268356-31:
(9*1)+(8*2)+(7*6)+(6*8)+(5*3)+(4*5)+(3*6)+(2*3)+(1*1)=175
175 % 10 = 5
So 1268356-31-5 is a valid CAS Registry Number.

An efficient, transition-metal-free process for the synthesis of substituted dihydrofurans via a Michael/cyclization tandem reaction

Wu, Ming-Yu,Wang, Ming-Qi,Li, Kun,Feng, Xing-Wen,He, Ting,Wang, Na,Yu, Xiao-Qi

, p. 679 - 683 (2011)

An efficient green route for the synthesis of substituted dihydrofurans was developed through a simple base-catalyzed, tandem reaction of nitrostyrene with 1,3-dicarbonyl compounds. The desired products were prepared with a large substrate scope and in excellent yields (up to 95%).
