131607-93-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131607-93-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,6,0 and 7 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 131607-93:
(8*1)+(7*3)+(6*1)+(5*6)+(4*0)+(3*7)+(2*9)+(1*3)=107
107 % 10 = 7
So 131607-93-7 is a valid CAS Registry Number.

The atropisomeric properties of seven-membered-ring benzolactams (7a-c and 8a) [1,5-benzodiazepin-2-one (a), 1,5-benzothiazepin-4-one (b), and 1-benzazepin-2-one (c)] were examined. The atropisomers were isolated as the diastereomers with an (S)-phenethyl
