Check Digit Verification of cas no

The CAS Registry Mumber 1211903-75-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,1,9,0 and 3 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1211903-75:
(9*1)+(8*2)+(7*1)+(6*1)+(5*9)+(4*0)+(3*3)+(2*7)+(1*5)=111
111 % 10 = 1
So 1211903-75-1 is a valid CAS Registry Number.

1H, 13C, 2D NMR and GCMS characterization of diol derivatives

Manivel,Khan, F. Nawaz

experimental part, p. 825 - 832 (2009/12/24)

Sodium borohydride (SBH) reduction of isocoumarins has been effected in presence of methanol to their respective diols. Diols have been isolated, purified and characterized by GCMS, proton, carbon and two-dimensional NMR spectroscopy analysis. Complete NMR assignments of diols are made using H-H COSY, as well as HSQC, HMQC and HMBC heteronuclear correlation techniques.
