55837-14-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 55837-14-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,8,3 and 7 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 55837-14:
(7*5)+(6*5)+(5*8)+(4*3)+(3*7)+(2*1)+(1*4)=144
144 % 10 = 4
So 55837-14-4 is a valid CAS Registry Number.

(Chemical Equation Presented) An alkylation of aminals with organozinc reagents derived from allyl bromide, benzyl bromide, α-bromoacetate, and α-bromonitrile proceeded efficiently in the presence of TMSCl and diisopropylamine. This reaction system was applied to the synthesis of an antispasmodic: butaverine.
