Check Digit Verification of cas no

The CAS Registry Mumber 104248-15-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,2,4 and 8 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 104248-15:
(8*1)+(7*0)+(6*4)+(5*2)+(4*4)+(3*8)+(2*1)+(1*5)=89
89 % 10 = 9
So 104248-15-9 is a valid CAS Registry Number.

SYNTHESIS OF DIHYDROTHIOPYRANS BY INTRAMOLECULAR WITTIG REACTION

Barreau, M.,Ponsinet, G.,Sante, Rhone-Poulenc

, p. 5451 - 5452 (1985)

The reaction of cyclopropylphosphonium salts with α-mercapto ketones, using the reported conditions for the reaction of an ω-functionalised carbonyl compound, failed to give the expected thiopyrans.An alternative procedure, which allowed the synthesis of
