Check Digit Verification of cas no

The CAS Registry Mumber 1222073-44-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,2,0,7 and 3 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1222073-44:
(9*1)+(8*2)+(7*2)+(6*2)+(5*0)+(4*7)+(3*3)+(2*4)+(1*4)=100
100 % 10 = 0
So 1222073-44-0 is a valid CAS Registry Number.

A facile chiral pool synthesis of (S)-6-nitroindoline-2-carboxylic acid from l -phenylalanine

Liu, Jin-Qiang,Qian, Chao,Chen, Xin-Zhi

, p. 403 - 406 (2010)

(S)-6-Nitroindoline-2-carboxylic acid, a substructure occurring in numerous biologically active natural products, was synthesized with moderate yield (53%) and high enantiomeric excess (>99.5%) starting from the nitration of l-phenylalanine, which is a commercially available chiral pool compound, followed by successively bromination and intramolecular cyclization. The route was carried out in gram quantities and it is suitable for industrial application due to its convenient reaction conditions and low cost. Georg Thieme Verlag Stuttgart - New York.
