Check Digit Verification of cas no

The CAS Registry Mumber 1315338-44-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,5,3,3 and 8 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1315338-44:
(9*1)+(8*3)+(7*1)+(6*5)+(5*3)+(4*3)+(3*8)+(2*4)+(1*4)=133
133 % 10 = 3
So 1315338-44-3 is a valid CAS Registry Number.

Divergent asymmetric synthesis of hexahydrobenzophenanthridine dopamine D1 agonists, A-86929, and dihydrexidine

Malhotra, Rajesh,Chakrabarti, Sagar,Ghosh, Amit,Ghosh, Rajib,Dey, Tushar K.,Dutta, Swarup,Dutta, Shantanu,Roy, Subho,Basu, Sourav,Hajra, Saumen

, p. 278 - 284 (2013/05/08)

A divergent and scalable asymmetric synthesis of the dopamine D1 agonists, A-86929, and dihydrexidine with high diastereo- and enantioselectivity was accomplished from Weinreb amide 8 derived from inexpensive and easily available l-serine. The synthesis of A-86929 involves only one chromatographic purification.

Asymmetric synthesis of a dopamine D1 agonist, dihydrexidine from d-serine

Malhotra, Rajesh,Ghosh, Amit,Ghosh, Rajib,Chakrabarti, Sagar,Dutta, Swarup,Dey, Tushar K.,Roy, Subho,Basu, Sourav,Hajra, Saumen

experimental part, p. 1522 - 1529 (2011/12/14)

A scalable asymmetric synthesis of trans-2-amino-6,7-dimethoxy-1- phenyltetralin 2 and its N-nosyl derivative 12 have been achieved from Garner aldehyde derived from easily available d-serine using a stereoselective PhMgBr addition, Wittig reaction and TF
