Check Digit Verification of cas no

The CAS Registry Mumber 55985-04-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,9,8 and 5 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 55985-04:
(7*5)+(6*5)+(5*9)+(4*8)+(3*5)+(2*0)+(1*4)=161
161 % 10 = 1
So 55985-04-1 is a valid CAS Registry Number.

Stereoselective synthesis of functional derivatives of 2-(2-carboxyethyl) pyrrolidine-2-carboxylic acid

Kudryavtsev,Nukolova,Kokoreva,Smolin

, p. 412 - 422 (2006)

Azomethine ylides generated from dimethyl 2-(arylmethylideneamino) pentanedioates by the action of AgOAc and Et3N reacted with dipolarophiles in regio- and stereoselective fashion to form 5-aryl-2-(2-carboxyethyl)pyrrolidine-2-carboxylic acid derivatives. 1,3-Dipolar cycloaddition of divinyl sulfone to the azomethine ylide generated from the Schiff base derived from methyl (S)-2-phthalimido-4-oxobutanoate and dimethyl glutamate gave chiral simplified kaitocephalin analogs. Pleiades Publishing, Inc., 2006.
