104310-02-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 104310-02-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,3,1 and 0 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 104310-02:
(8*1)+(7*0)+(6*4)+(5*3)+(4*1)+(3*0)+(2*0)+(1*2)=53
53 % 10 = 3
So 104310-02-3 is a valid CAS Registry Number.

A series of 5-formyl derivatives was synthesized by formylation of 2,3,4,5-tetrahydro-1H-1,5-benzodiazepin-2-ones with a mixture of formic acid and acetic anhydride.The structure of their rotation isomers was studied by PMR spectroscopy.
