Check Digit Verification of cas no

The CAS Registry Mumber 123784-50-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,7,8 and 4 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 123784-50:
(8*1)+(7*2)+(6*3)+(5*7)+(4*8)+(3*4)+(2*5)+(1*0)=129
129 % 10 = 9
So 123784-50-9 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 (2007/10/02)

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.
