Check Digit Verification of cas no
The CAS Registry Mumber 826-10-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,2 and 6 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 826-10:
(5*8)+(4*2)+(3*6)+(2*1)+(1*0)=68
68 % 10 = 8
So 826-10-8 is a valid CAS Registry Number.

Trace decomposition of selegiline. Use of worst-case kinetics for a stable drug
Chafetz,Desai,Sukonik
, p. 1250 - 1252 (2007/10/02)
A solution of selegiline hydrochloride reference standard, which contained no detectable impurities at the time of its preparation, was found by HPLC to contain a trace of a compound at the locus of methamphetamine when analyzed after 1 year. Heating selegiline solutions at pH 7 and 105 °C produced methamphetamine as the major product at a rate which closely followed the first-order rate equation. Using only these data and worst-case assumptions, rate constants were estimated at various temperatures; the activation energy was estimated to be about 25 kcal, and the stability-indicating validity of the assay used was reaffirmed. Selegiline undergoes degradation at a negligibly slow rate.
