Check Digit Verification of cas no

The CAS Registry Mumber 393837-14-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,9,3,8,3 and 7 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 393837-14:
(8*3)+(7*9)+(6*3)+(5*8)+(4*3)+(3*7)+(2*1)+(1*4)=184
184 % 10 = 4
So 393837-14-4 is a valid CAS Registry Number.

Optimized synthesis of tetrahydroisoquinoline-hydantoins

Charton, Julie,Gassiot, Amaury Cazenave,Melnyk, Patricia,Girault-Mizzi, Sophie,Sergheraert, Christian

, p. 7081 - 7085 (2007/10/03)

Several methods have been developed and compared for the solution synthesis of tetrahydroisoquinoline-hydantoin derivatives. The best yields were obtained when the imidazolidine-2,4-dione ring was synthesized in two steps: (1) reaction of Tic-OH with the appropriate amine and (2) cyclization with 1,1′-carbonyldiimidazole.
