Check Digit Verification of cas no

The CAS Registry Mumber 6581-54-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,5,8 and 1 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 6581-54:
(6*6)+(5*5)+(4*8)+(3*1)+(2*5)+(1*4)=110
110 % 10 = 0
So 6581-54-0 is a valid CAS Registry Number.

HIGH YIELD PREPARATION OF 2,3,3-TRICHLORINATED TETRAHYDROPYRAN WITH AN EXCESS OF REFLUXING SULFURYL CHLORIDE IN THE DARK

Buyck, Laurent de

, p. 303 - 306 (2007/10/02)

The chlorination of tetrahydropyran with an excess of refluxing sulfuryl chloride in the dark provided 2,3,3-trichlorotetrahydropyran in 94percent isolated yield, showing evidence for a very selective non-homolytic mechansims, probably involving hydride abstraction as the first step.
