Check Digit Verification of cas no

The CAS Registry Mumber 747-59-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,4 and 7 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 747-59:
(5*7)+(4*4)+(3*7)+(2*5)+(1*9)=91
91 % 10 = 1
So 747-59-1 is a valid CAS Registry Number.

FACILE SYNTHETIC METHODS OF ACETALS AND CROWN ETHERS FROM THE REACTION OF DIPHENYLDIAZOMETHANE WITH 2,3-DICHLORO-5,6-DICYANOBENZOQUINONE IN THE PRESENCE OF ALCOHOLS

Oshima, Takumi,Nishioka, Ryoji,Nagai, Toshikazu

, p. 3919 - 3922 (1980)

The reaction of diphenyldiazomethane with 2,3-dichloro-5,6-dicyanobenzoquinone in the presence of alcohols and thiols gave the corresponding benzophenone acetals and thioacetals at 20-25 deg C in 1,2-dichloroethane.The mechanism of the reaction will be discussed.
