72-20-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 72-20-8 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 7 and 2 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 72-20:
(4*7)+(3*2)+(2*2)+(1*0)=38
38 % 10 = 8
So 72-20-8 is a valid CAS Registry Number.

Evaluation of lipase from Candida rugosa in the resolution of endo- (±)- 1,8,9,10,11,11-hexachloropentacyclo- [6.2.1.13,6.02,7.05,9]dodecan-4-alcohol

Costa, Valentim E. U.,Alifantes, Joao,Martins, Jose E. D.

, p. 2579 - 2585 (1998)

endo-(±)-1,8,9,10,11,11- Hexachloropentacyclo[6.2.1.13,6.02,7.05,9)]dodecan-4-ol (±)-7 and exo-(±)1,8,9,10,11,11- hexachloropentacyclo[6.2.1.13,6,02,7.05,9]dodecan-4-ol (±)-4 have been prepared and the enantiomeric enrichment capacity of the lipase from Candida rugosa in the transesterification with vinyl acetate of these compounds was evaluated. It was verified that the lipase recognize only the alcohol (±)-7, producing endo-(+)- 1,8,9,10,11,11- hexachloropentacyclo[6.2.1.13,6.02,7.05,9]dodecan-4-yl acetate (+)- 8 with ee >95% and conversion of 44% as the only product.
