77-04-3 Usage
Uses
Used in Pharmaceutical Industry:
Pyrithyldione is used as an intermediate in the synthesis of sedative/hypnotic drugs for the treatment of insomnia. Its chemical properties allow it to be a crucial component in the creation of Methyprylon (M338670), a medication that helps alleviate sleep disorders and promotes restful sleep.
Additionally, Pyrithyldione is used as a hypnotic and sedative agent in the pharmaceutical industry. Its calming effects make it a valuable asset in the development of medications aimed at reducing anxiety and promoting relaxation.
Check Digit Verification of cas no
The CAS Registry Mumber 77-04-3 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 7 and 7 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 77-04:
(4*7)+(3*7)+(2*0)+(1*4)=53
53 % 10 = 3
So 77-04-3 is a valid CAS Registry Number.

, p. 8063 - 8066 (2007/10/03)
A new procedure for protecting the amide, lactam, urea, and carbamate NH group with a triphenylmethyl (Tr) group is described. The utility of this method is illustrated with molecules that contain other functional groups. A mild deprotection using trifluoroacetic acid makes this a useful method for attaching amide groups on resin for combinatorial synthesis.
