Check Digit Verification of cas no
The CAS Registry Mumber 21902-40-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,9,0 and 2 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 21902-40:
(7*2)+(6*1)+(5*9)+(4*0)+(3*2)+(2*4)+(1*0)=79
79 % 10 = 9
So 21902-40-9 is a valid CAS Registry Number.

Examples of hydroxymethylated analogues of heteroaryl cores such as quinazolin-4-ones, isoquinolin-1(2H)-ones, pyrido[3,4-d]pyrimidin-4(3H)-ones, chromen-4-ones and pyrrolo[2,1-f][1,2,4]triazin-4(3H)-ones are sparse or non-existent in the scientific literature. We have demonstrated that such compounds are accessible by using standard procedures from readily available raw materials.
