Check Digit Verification of cas no

The CAS Registry Mumber 182155-66-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,2,1,5 and 5 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 182155-66:
(8*1)+(7*8)+(6*2)+(5*1)+(4*5)+(3*5)+(2*6)+(1*6)=134
134 % 10 = 4
So 182155-66-4 is a valid CAS Registry Number.

Regioselective synthesis of partially protected trehalose analogues and assignment of ring size in isopropylidene acetal derivatives by 13C NMR spectroscopy

Bassily, Rafik W.,Youssef, Rimon H.,El-Sokkary, Ramadan I.,Nashed, Mina A.

, p. 653 - 663 (2007/10/03)

The 13C NMR spectra of a range of di-O-isopropylidene acetals of α,α-trehalose and its analogues 1, 2, 4-7 have been studied. Attention has been focussed on the chemical shifts of the acetal carbon and methyl groups of the acetals. These parame
