Check Digit Verification of cas no

The CAS Registry Mumber 309926-41-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,9,9,2 and 6 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 309926-41:
(8*3)+(7*0)+(6*9)+(5*9)+(4*2)+(3*6)+(2*4)+(1*1)=158
158 % 10 = 8
So 309926-41-8 is a valid CAS Registry Number.

A facile and one-pot synthesis of pyrone derivatives via ionic liquid catalysed knoevenagel reaction and their biological evaluation

Vijaya Bhaskar,Joshi, Shrinivas D.,Ahuja, Priyanka

, p. 225 - 230 (2019/01/18)

A series of novel pyrone derivatives was synthesized by using a green chemistry approach i.e. by the use of an ionic liquid, 1-butyl-3-methylimidazolium bromide. The three component one-pot synthesis of pyrone involves the Knoevenagel condensation reactio
