Check Digit Verification of cas no
The CAS Registry Mumber 51638-93-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,6,3 and 8 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 51638-93:
(7*5)+(6*1)+(5*6)+(4*3)+(3*8)+(2*9)+(1*3)=128
128 % 10 = 8
So 51638-93-8 is a valid CAS Registry Number.

7α-Hydroxy-6β-(3-oxo-4-phenoxy-1E-butenyl)-2-oxabicyclooctan-3-one was synthesized by the selective oxidation of 7α-hydroxy-6β-hydroxymethylene-2-oxabicyclooctan-3-one bistrimethylsilyl ether with CrO3*2Py/SiO2 and subsequent condensation of the intermediate 7α-trimethylsiloxy-6β-formyl-2-oxabicyclooctan-3-one with dimethyl 2-oxo-3-phenoxypropylphosphonate.The product was then converted into the methanesulfonamide of 16-phenoxy-17,18,19,20-tetranorprostaglandin E2 (sulprostone).
