Check Digit Verification of cas no

The CAS Registry Mumber 1003217-17-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,0,3,2,1 and 7 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1003217-17:
(9*1)+(8*0)+(7*0)+(6*3)+(5*2)+(4*1)+(3*7)+(2*1)+(1*7)=71
71 % 10 = 1
So 1003217-17-1 is a valid CAS Registry Number.

Intramolecular hydrogen bonding and anion binding of N-benzamido-N′- benzoylthioureas

Liu, Wen-Xia,Jiang, Yun-Bao

, p. 1124 - 1127 (2008/09/18)

(Chemical Equation Presented) N-(p-Dimethylamino)benzoyl-N′- phenylthiourea as an N-acylthiourea is known to be unable to bind anions due to a strong intramolecular hydrogen bond (IHB). We show here that by inserting an amido group in the N′-phenyl side the newly designed N-benzamido-N′- benzoylthioureas, despite this IHB too, bind strongly to anions with binding constants on the order of 106-107 mol-1 L. Results suggest that potential anion receptors or organocatalysts could be developed on the basis of this framework with a wide structural diversity.
