Check Digit Verification of cas no

The CAS Registry Mumber 218440-81-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,8,4,4 and 0 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 218440-81:
(8*2)+(7*1)+(6*8)+(5*4)+(4*4)+(3*0)+(2*8)+(1*1)=124
124 % 10 = 4
So 218440-81-4 is a valid CAS Registry Number.

Synthesis of 17β-isoxazolyl steroids and spiro[steroid-17,2′-furanone]s

Baranovsky, Alexander V.,Groen, Marinus B.,De Groot, Aede,Litvinovskaya, Raissa P.,Khripach, Vladimir A.

, p. 1564 - 1574 (1998)

Synthesis of 17β-isoxazolyl steroids and their transformations into the corresponding spiro[steroid-17,2′-furanone]s are described. The reaction sequence consists of the 1,3-dipolar cycloaddition of a nitrile oxide to mestrenol, dehydration, epoxidation or dihydroxylation, cleavage of the isoxazole moiety and cyclization of intermediate enamino ketones.
