Check Digit Verification of cas no

The CAS Registry Mumber 153219-69-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,3,2,1 and 9 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 153219-69:
(8*1)+(7*5)+(6*3)+(5*2)+(4*1)+(3*9)+(2*6)+(1*9)=123
123 % 10 = 3
So 153219-69-3 is a valid CAS Registry Number.

Synthesis of a 'reverse ester' analogue of 1,2-sn-diglycerides from (S)-1,2-di-O-isoprophylideneglycerol; efficient, stereospecific nucleophilic displacement via a triflate at glycerol C-2

Golding, Bernard T.,Griffin, Alice L.,Robinson, David H.

, p. 6459 - 6462 (2007/10/02)

An optically pure glyceride analogue in which the 2-O-ester grouping has been reversed was efficiently synthesised from (S)-di-O-isopropylideneglycerol by a sequence that featured an SN 2 displacement by the anion of diethyl malonate on a protected glycerol 2-O-triflate.
