Uses

Vitamin D2 O-t-Butyldimethylsilyl Ether is an impurity of Vitamin D2 (V676040), which is a synthetic form of Vitamin D. Prepared from ergosterol by UV irradiation in a suitable solvent. Commercial solutions are usually made with propylene glycol or sesame oil. Antirachitic.Vitamin D2 O-t-Butyldimethylsilyl Ether is also an intermediate in synthesizing (7Z)-Calcipotriene (C144225), which is an isomeric impurity of Calcipotriene (1442000), a vitamin D3 analogue with low calcemic activity.

Check Digit Verification of cas no

The CAS Registry Mumber 104846-62-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,8,4 and 6 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 104846-62:
(8*1)+(7*0)+(6*4)+(5*8)+(4*4)+(3*6)+(2*6)+(1*2)=120
120 % 10 = 0
So 104846-62-0 is a valid CAS Registry Number.
