Check Digit Verification of cas no

The CAS Registry Mumber 1174624-67-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,4,6,2 and 4 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1174624-67:
(9*1)+(8*1)+(7*7)+(6*4)+(5*6)+(4*2)+(3*4)+(2*6)+(1*7)=159
159 % 10 = 9
So 1174624-67-9 is a valid CAS Registry Number.

Formation of 5-alkylidenepyrazol-4(1H)-ones and 3-amino-6-aryl-5-cyano- pyridazine-4-carboxylates from arenealdehyde thiosemicarbazones and unsaturated 1,2-diesters

Hassan, Alaa A.,Shehata, Hamdy S.,Doepp, Dietrich

experimental part, p. 725 - 730 (2009/09/25)

The reaction of arenealdehyde 4-phenylthiosemicarbazones la-f with dimethyl ethynedicarboxylate (6) gave methyl [3-aryl-4-oxo-1-(phenylthiocarbamoyl)-4,5- dihydro-1H-pyrazol-5-ylidene]ethanoates 10a-f in 73-79% yield, while, by reaction with diethyl (E)-2
