Check Digit Verification of cas no
The CAS Registry Mumber 119302-20-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,3,0 and 2 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 119302-20:
(8*1)+(7*1)+(6*9)+(5*3)+(4*0)+(3*2)+(2*2)+(1*0)=94
94 % 10 = 4
So 119302-20-4 is a valid CAS Registry Number.

A new and efficient method for the synthesis of rocuronium bromide

Rocuronium bromide has been used as an aminosteroid non-depolarizing neuromuscular blocker and muscle relaxant. In this work, a new and efficient route for preparing a key intermediate 2β-(4-morpholinyl)-16β-(1-pyrrolidinyl)-5α-androstan-3α,17β-diol (6) was developed through a ring-opening of epoxide followed by introducing and pyrrolidine. Compound 6 can easily provide rocuronium bromide and the overall yield of compound 6 in 5 steps increased to 57.8%, which was higher than currently reported methods. Extraordinarily, this method would avoid the generation of disubstituted impurities E and F which are difficult to remove.
