Check Digit Verification of cas no

The CAS Registry Mumber 1262053-61-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,2,0,5 and 3 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1262053-61:
(9*1)+(8*2)+(7*6)+(6*2)+(5*0)+(4*5)+(3*3)+(2*6)+(1*1)=121
121 % 10 = 1
So 1262053-61-1 is a valid CAS Registry Number.

Synthesis of [2H4]oxymetazoline and [ 14C]oxymetazoline

Brugger, Michelle L.,Borges, Scott,Ren, Sumei,McNamara, Paul

, p. 793 - 795 (2010)

An efficient synthesis of [2H4] and [ 14C]oxymetazoline has been developed. Both compounds follow the same synthetic route with the introduction of the label occurring at different synthetic steps. The synthesis of [2H4]oxymetazoline from [2H4]ethylene diamine was achieved in one step with a 40% yield. The synthesis of [14C]oxymetazoline from potassium [ 14C]cyanide was achieved in two steps with an overall radiochemical yield of 67%. Copyright
