Check Digit Verification of cas no

The CAS Registry Mumber 156043-74-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,0,4 and 3 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 156043-74:
(8*1)+(7*5)+(6*6)+(5*0)+(4*4)+(3*3)+(2*7)+(1*4)=122
122 % 10 = 2
So 156043-74-2 is a valid CAS Registry Number.

Total synthesis of halichondrin B from common sugars: An F-ring intermediate from D-glucose and efficient construction of the C1 to C21 segment

Cooper,Pan,Salomon

, p. 8193 - 8196 (2007/10/02)

An F-ring intermediate 7, with correct absolute configurations for the stereocenters at positions 17 and 20 of halichondrin B, is readily available from D-glucose. The practical utility of methoxybenzyl furanoside derivatives was demonstrated during incorporation of 7 into an acid-sensitive C1 to C21 segment.
