76798-65-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 76798-65-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,7,9 and 8 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 76798-65:
(7*7)+(6*6)+(5*7)+(4*9)+(3*8)+(2*6)+(1*5)=197
197 % 10 = 7
So 76798-65-7 is a valid CAS Registry Number.

, (2008/06/13)
The invention concerns a levulinic acid addition salt of the antihypertensive agent 4-amino-6,7-dimethoxy-2-[4-(5-methylthio-1,3,4-oxadiazole-2-carbonyl]piperazin-1-yl)quinazoline in which the base to acid mole ratio is 1 to from 1.25-1.35. The salt is characterized in having improved water solubility and stability compared to the levulinate salt having a 1:1 ratio of base to acid.
