Check Digit Verification of cas no

The CAS Registry Mumber 1355249-21-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,5,2,4 and 9 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1355249-21:
(9*1)+(8*3)+(7*5)+(6*5)+(5*2)+(4*4)+(3*9)+(2*2)+(1*1)=156
156 % 10 = 6
So 1355249-21-6 is a valid CAS Registry Number.

, (2012/02/02)

The present invention describes and claims compounds of the Structural Formula I, Structural Formula II, or Structural Formula III: wherein R1, R2, R3 and R3' are -H or methyl, or R3 and R3 taken together form a double bond, or R3' is -H and R2 and R3 taken together form a spiro-cyclopropyl substituent, R4 is -H or -F, and R5 is -H, methyl, -CI or -Br, Formula II wherein R1 is -H, ethyl-, isopropyl-, cyclopropyl-, methyl- or methoxy-, R4 is -H or -F, and "Y" is: (a) -CH2-; (b) -CR6H-0-CR7R8-, wherein R6, R7, and R8 are independently - H or methyl; (c) -CR6H-N(R9)-CR7R8-, wherein R6, R7, and R8 are independently -H or methyl; (d) -CH2-C(R9)(R10)-C(R7)(R8)-, wherein R7, R8, R9 and R10 are independently - H or -methyl, or both R7 and R8 are -F, R9 and R10 are independently -H or -methyl, or both R9 and R10 are -F, or R9 and R10 taken together are (0=), which together with the carbon to which they are attached forms a carbonyl group.
