Check Digit Verification of cas no

The CAS Registry Mumber 697752-34-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,9,7,7,5 and 2 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 697752-34:
(8*6)+(7*9)+(6*7)+(5*7)+(4*5)+(3*2)+(2*3)+(1*4)=224
224 % 10 = 4
So 697752-34-4 is a valid CAS Registry Number.

Stereoselective synthesis of D-desosamine and related glycals via tungsten-catalyzed alkynol cycloisomerization

Davidson, Mary H.,McDonald, Frank E.

, p. 1601 - 1603 (2007/10/03)

Stereoselective synthesis of D-desosamine diacetate ester (iii, R = Ac) was achieved from the glycal (ii) generated by tungsten carbonyl-catalyzed cycloisomerization of the corresponding amino-alkynol (i). A wide variety of N-substituents (R, R′) are compatible with the cycloisomerization, provided that at least one R or R′ is an acyl derivative.
