Check Digit Verification of cas no

The CAS Registry Mumber 167844-89-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,7,8,4 and 4 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 167844-89:
(8*1)+(7*6)+(6*7)+(5*8)+(4*4)+(3*4)+(2*8)+(1*9)=185
185 % 10 = 5
So 167844-89-5 is a valid CAS Registry Number.

Cladinose analogues of sixteen-membered macrolide antibiotics. VI. Synthesis of metabolically programmed, highly potent analogues of sixteen-membered macrolide antibiotics

, p. 771 - 785 (1998)

Five novel 3-hydroxyl derivatives of sixteen-membered macrolide possessing 4-O-acyl-α-L-cladinose as a neutral sugar moiety were synthesized by using a combination of structurally stable silyl acetal protection and selective hydrogenolysis of a 3'-methylthiomethyl ether to a 3'-OMe group. Several derivatives having n-butyryl, i-butyryl and n-valeryl substituent at the 4'-OH group exhibited significant antibacterial activity in vitro. One of them, 4'-O-n-butyryl-3'-O-methylleucomycin V, showed improved therapeutic effect in mice.
