Check Digit Verification of cas no

The CAS Registry Mumber 94057-07-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,0,5 and 7 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 94057-07:
(7*9)+(6*4)+(5*0)+(4*5)+(3*7)+(2*0)+(1*7)=135
135 % 10 = 5
So 94057-07-5 is a valid CAS Registry Number.

Synthesis and antiallergic activity of dimethyl-2- (phenylcarbamoyl)ethylsulfonium p-toluenesulfonate derivatives

Tada, Yukio,Yamawaki, Ichiro,Ueda, Shuichi,Matsumoto, Hiroshi,Matsuura, Naosuke,Yasumoto, Mitsugi,Koda, Akihide,Hori, Mikio

, p. 3330 - 3336 (2007/10/03)

The derivatives of dimethyl-2-(phenylcarbamoyl)ethylsulfonium p- toluenesulfonates were synthesized and evaluated for antiallergic activity. The 2,3-dihydroxyethoxy group was introduced to the phenyl ring from the standpoint of lipophilicity and electronic effects of substituent. The IgE- induced rat passive cutaneous anaphylaxis (PCA) was inhibited by oral administration of several substituted 2-[(4- propoxyphenyl)carbamoyl]ethyldimethylsulfonium p-toluenesulfonate derivatives. Among them (±)-2-[N-[4-(3-ethoxy-2- hydroxypropoxy)phenyl]carbamoyl]ethyldimethylsulfonium p-toluenesulfonate (1a, IPD-1151T) was found to possess considerable activity in the PCA test, and it was launched as Suplatast tosilate in Japan.
