General Description
Pharmaceutical secondary standards for application in quality control provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards
Purification Methods
Wash it with 50% HCl and distil it under reduced pressure just before use. It has UV: 234nm (hexane). The Z-oxime has m 144o, 136-138o and 142o (H2O). [Beilstein
Check Digit Verification of cas no
The CAS Registry Mumber 98-03-3 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 9 and 8 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 98-03:
(4*9)+(3*8)+(2*0)+(1*3)=63
63 % 10 = 3
So 98-03-3 is a valid CAS Registry Number.
