Check Digit Verification of cas no

The CAS Registry Mumber 75724-97-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,7,2 and 4 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 75724-97:
(7*7)+(6*5)+(5*7)+(4*2)+(3*4)+(2*9)+(1*7)=159
159 % 10 = 9
So 75724-97-9 is a valid CAS Registry Number.

Aspects of Tautomerism: Part X - Neighbouring Group Effects on the Structure and Reactivity Patterns of Acid Chlorides

Bhatt, M. Vivekananda,El Ashry, Shaker H.,Somayaji, Vishwanatha

, p. 473 - 486 (2007/10/02)

The influence of neighbouring groups on the structure and reactivity patterns of over one hundred acid chlorides derived from γ- and δ-keto acids, 1,2- and 1,3-dicarboxylic acid half-esters and diacid chlorides have been examined.Contrary to reports in the literature, text books and monographs, evidence has been obtained for the non-existence of tautomerism between the isomeric pairs of either acid chlorides or half-ester acid chlorides.ce.
