Check Digit Verification of cas no

The CAS Registry Mumber 98239-15-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,2,3 and 9 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 98239-15:
(7*9)+(6*8)+(5*2)+(4*3)+(3*9)+(2*1)+(1*5)=167
167 % 10 = 7
So 98239-15-7 is a valid CAS Registry Number.

Reactions of Diaminosulfoxonium Ylides with Aldehydes. Preparation of Cyclopropyldiaminosulfoxonium Salts

Okuma, Kentaro,Sato, Yasunari,Ohta, Hiroshi,Yokomori, Yoshinobu

, p. 1855 - 1862 (2007/10/02)

The reaction of diaminosulfoxonium ylides with aldehydes gave the corresponding cyclopropyldiaminosulfoxonium salts in good yields when 1,8-diazabicycloundec-7-ene (DBU) was used as a base.These ylides reacted with aldehydes to give the corresponding betaines, which resulted in the formation of vinylsulfoxonium salts.The additional ylides reacted with these salts to afford cyclopropylsulfoxonium salts.The reaction of these salts with potassium hydroxide is also described.

SYNTHESIS OF CYCLOPROPYLAMINOOXOSULFONIUM SALTS BY THE REACTION OF DIAMINOOXOSULFONIUM YLIDES WITH ALDEHYDES

Okuma, Kentaro,Nakanishi, Kazuto,Honda, Takumi,Ohta, Hiroshi,Yokomori, Yoshinobu,Sekido, Kiyotane

, p. 333 - 336 (2007/10/02)

The title compounds have been synthesized by the reaction of diaminooxosulfonium methylides with aldehydes as isomeric mixtures in good yields.These ylides reacted with aldehydes to give betaines, which formed unusual four-membered cyclic alkoxyoxosulfonium salts.Another methylide further attacked α-carbon of these salts to afford cyclopropyldiaminooxosulfonium salts.
