The CAS Registry Mumber 68999-77-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,9,9 and 9 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 68999-77:
(7*6)+(6*8)+(5*9)+(4*9)+(3*9)+(2*7)+(1*7)=219
219 % 10 = 9
So 68999-77-9 is a valid CAS Registry Number.

REACTION ON SOLID SUPPORT PART V: THE MECHANISM OF OXIDATION OF α-METHYLPYRROLES TO α-FORMYLPYRROLES BY TALLIUM NITRATE ON CLAY

Jackson, Anthony H.,Nagaraja Rao, K. R.,Smeaton, Elizabeth

, p. 2673 - 2676 (1989)

Evidence is presented to show that the clay-catalyzed thallium nitrate oxidation of α-methylpyrroles to α-formylpyrroles involves formation of an intermediate nitrate ester which subsequently undergoes elimination of nitrite.
