Check Digit Verification of cas no

The CAS Registry Mumber 1768-64-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,6 and 8 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1768-64:
(6*1)+(5*7)+(4*6)+(3*8)+(2*6)+(1*4)=105
105 % 10 = 5
So 1768-64-5 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.
