It is also known as diltiazem, a medication used to treat high blood pressure and chest pain caused by angina. Diltiazem works by relaxing the blood vessels and increasing the supply of blood and oxygen to the heart. It belongs to the class of drugs called calcium channel blockers, which help to lower blood pressure and reduce the workload on the heart.

Check Digit Verification of cas no
The CAS Registry Mumber 138890-97-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,8,9 and 0 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 138890-97:
(8*1)+(7*3)+(6*8)+(5*8)+(4*9)+(3*0)+(2*9)+(1*7)=178
178 % 10 = 8
So 138890-97-8 is a valid CAS Registry Number.
