Check Digit Verification of cas no
The CAS Registry Mumber 131013-15-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,0,1 and 3 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 131013-15:
(8*1)+(7*3)+(6*1)+(5*0)+(4*1)+(3*3)+(2*1)+(1*5)=55
55 % 10 = 5
So 131013-15-5 is a valid CAS Registry Number.

Synthesis of 3-carbamoylecgonine methyl ester analogues as inhibitors of cocaine binding and dopamine uptake
Kline Jr.,Wright,Eshleman,Fox,Eldefrawi
, p. 702 - 705 (2007/10/02)
Five (1R-2-exo-3-exo)-3-(N-phenylcarbamoyl)ecgonine methyl ester analogues were synthesized and characterized by 1H and 13C NMR, IR, and thermospray MS. The compounds were synthesized in two or three steps as (-)-stereoisomers from (
