Check Digit Verification of cas no
The CAS Registry Mumber 90822-23-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,8,2 and 2 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 90822-23:
(7*9)+(6*0)+(5*8)+(4*2)+(3*2)+(2*2)+(1*3)=124
124 % 10 = 4
So 90822-23-4 is a valid CAS Registry Number.

Page/Page column 15-16, (2010/11/28)
The invention relates to a process for the preparation of meropenem, a β-methylcarbopenem. The said process comprises the following steps: preparing the compound of Formula (XI) from the compound of Formula (IV) through three steps "one-pot process"; then condensing the compound of Formula (XI) with the compound of Formula (XX) to form the compound of Formula (XXIV); finally preparing meropenam of Formula (I) from the compound of Formula (XXIV) by deprotection reaction by means of catalyst. The process of the invention is easily to carry out, the product is isolated in high content and yield, and the cost is reduced, thereby overcoming the shortage of the prior art.
