64550-88-5 Usage
Chemical Properties
white fine crystalline powder
Purification Methods
Purify sinigrin by recrystallising it three times from EtOH and once from MeOH. The tetraacetate has m 193-195o, [] D 20 -16o (c 0.14, H2O). [Benn et al. J Chem Soc, Chem Commun 445 1965, Kjaer et al. Acta Chem Scand 10 432 1956, Marsh et al. Acta Cryst (Sect B ) 26 1030 1970.] It is a -D-thioglucopyranoside substrate for thiogluconidase [MacLeod & Rossiter Phytochem 25 1047 1986]. [Beilstein 31 H 476, 17 III/IV 3738.]
Check Digit Verification of cas no
The CAS Registry Mumber 64550-88-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,5,5 and 0 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 64550-88:
(7*6)+(6*4)+(5*5)+(4*5)+(3*0)+(2*8)+(1*8)=135
135 % 10 = 5
So 64550-88-5 is a valid CAS Registry Number.
