Check Digit Verification of cas no

The CAS Registry Mumber 344408-05-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,4,4,0 and 8 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 344408-05:
(8*3)+(7*4)+(6*4)+(5*4)+(4*0)+(3*8)+(2*0)+(1*5)=125
125 % 10 = 5
So 344408-05-5 is a valid CAS Registry Number.

Aerobic synthesis of pyrroles and dihydropyrroles from imines: Palladium(II)-catalyzed intramolecular C-H dehydrogenative cyclization

Shi, Zhuangzhi,Suri, Mamta,Glorius, Frank

supporting information, p. 4892 - 4896 (2013/06/04)

sp3ectacularly mild! An efficient PdII-catalyzed intramolecular dehydrogenative cyclization of imines affords (dihydro)pyrrole products using molecular oxygen as the sole oxidant. This mild formal sp 3-C-H functionalization allows rapid and atom-economical assembly of (dihydro)pyrrole rings from inexpensive and readily available allylamines and ketones. A broad range of functional groups are tolerated. Copyright
