Check Digit Verification of cas no

The CAS Registry Mumber 20779-63-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,7,7 and 9 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 20779-63:
(7*2)+(6*0)+(5*7)+(4*7)+(3*9)+(2*6)+(1*3)=119
119 % 10 = 9
So 20779-63-9 is a valid CAS Registry Number.

Kinetics and Mechanism of Reactions of Amides with Formaldehyde

Nair, B. Raveendran,Francis, Joseph

, p. 159 - 161 (2007/10/02)

Kinetics of the reactions of substituted ureas like methylurea, phenylurea, acetamide and benzamide with formaldehyde have been studied, using a TLC method developed for the purpose.The increased reactivity of methylurea towards formaldehyde, as compared to urea, is due to the electron-releasing nature of the methyl group.The reduced reactivity of phenylurea is due to the electron-withdrawing nature of the phenyl group.The reduced reactivity observed in the case of acetamide and benzamide is also explained.
