Check Digit Verification of cas no
The CAS Registry Mumber 68020-98-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,0,2 and 0 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 68020-98:
(7*6)+(6*8)+(5*0)+(4*2)+(3*0)+(2*9)+(1*8)=124
124 % 10 = 4
So 68020-98-4 is a valid CAS Registry Number.

Zinc tetrafluoroborate-catalyzed efficient conversion of aldehydes to geminal diacetates and cyanoacetates
Ranu, Brindaban C.,Dutta, Jyotirmoy,Das, Arijit
, p. 366 - 367 (2007/10/03)
A trace of an aqueous solution of zinc tetrafluoroborate was demonstrated to catalyze the conversion of an aldehyde to its 1,1-diacetate by acetic anhydride without any solvent. A similar reaction of an aldehyde with a mixture of potassium cyanide and acetic anhydride in methylene chloride was also catalyzed by Zn(BF4)2 to provide the corresponding geminal cyanoacetate.
