Check Digit Verification of cas no

The CAS Registry Mumber 1273545-12-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,7,3,5,4 and 5 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1273545-12:
(9*1)+(8*2)+(7*7)+(6*3)+(5*5)+(4*4)+(3*5)+(2*1)+(1*2)=152
152 % 10 = 2
So 1273545-12-2 is a valid CAS Registry Number.

Stereoselective synthesis and characterization of (Z)-(-)-4-(1′- Alkoxyl-1′-alkyloxycarbonyl-methylidene)-5(R)-[(1R)-menthyloxy] - Butyrolactones

Feng, Zhiqiang,Yin, Chenglie

, p. 507 - 515 (2011/04/16)

A series of enantiomerically pure (Z)-(-)-4-(1′-alkyloxy-1′- alkyloxycarbonylmethylidene)- 5(R)-[(1R)-menthyloxy]-c-butyrolactones were synthesized and characterized in good to excellent yields via O-alkylation of (4R,5R)-(-)-4-ethoxyoxalyl-5-[(1R)- menthyloxy]-γ-butyrolactone with alkyl halides in the presence of K2CO3 in acetone at room temperature.
