Check Digit Verification of cas no

The CAS Registry Mumber 29780-80-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,7,8 and 0 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 29780-80:
(7*2)+(6*9)+(5*7)+(4*8)+(3*0)+(2*8)+(1*0)=151
151 % 10 = 1
So 29780-80-1 is a valid CAS Registry Number.

THE PHTHALATION OF 2-AMINO-2-DEOXY-D-GLUCOSE AND N-METHYL-1-AMINO-1-DEOXY-D-GLUCITOL; CONVERSION OF THE PRODUCTS TO ORGANOTIN DERIVATIVES. A READY MIGRATION OF ACETYL FROM OXYGEN TO NITROGEN UNDER NEUTRAL CONDITIONS

Patel, Atula,Poller, Robert C.

, p. 182 - 184 (2007/10/02)

N-Phthalation of 3-amino-3-deoxy-D-glucose was followed by replacement of the acidic proton by tributyl- and triphenylstannyl groups.A similar reaction with 1-(methylamino)-1-deoxy-D-glucitol failed and successive treatment with benzyl chloroformate and acetic anhydride followed by catalytic hydrogenation showed that a 1,4-O->N acetyl migration had occured.Phthalation and stannylation succeeded under different conditions.
