Check Digit Verification of cas no

The CAS Registry Mumber 130232-56-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,2,3 and 2 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 130232-56:
(8*1)+(7*3)+(6*0)+(5*2)+(4*3)+(3*2)+(2*5)+(1*6)=73
73 % 10 = 3
So 130232-56-3 is a valid CAS Registry Number.

A general, practical, and versatile strategy for accessing ω- functional 1,2-diols of high enantiomeric excess

Dispiroketals in synthesis (part 9): Resolution of 1,2-diols using a C2-symmetric diphenyltetrahydrobipyran

Edwards,Entwistle,Ley,Owen,Perry

, p. 553 - 556 (2007/10/02)

A series of 1,2-diols were resolved by the enantioselective formation of the thermodynamically most stable dispiroketal using (2R,2'R) and (2S,2'S) 2,2'-diphenyl-3,3',4,4'-tetrahydro-6,6'-bi-2H-pyran 2 and 3. Deprotection was achieved using a metal ammonia reduction to liberate the resolved diols.
