Check Digit Verification of cas no
The CAS Registry Mumber 1246819-04-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,6,8,1 and 9 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1246819-04:
(9*1)+(8*2)+(7*4)+(6*6)+(5*8)+(4*1)+(3*9)+(2*0)+(1*4)=164
164 % 10 = 4
So 1246819-04-4 is a valid CAS Registry Number.

Three stable and simple synthetic routes of labeled D9-Mabuterol, D9-Bambuterol, and D9-Cimbuterol were described with 98.5%, 99.7%, and 98.4% isotopic abundance and good purity. These structures and isotope-abundance were confirmed according to 1H NMR and liquid chromatography-tandem mass spectrometry.
