Check Digit Verification of cas no
The CAS Registry Mumber 28437-33-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,4,3 and 7 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 28437-33:
(7*2)+(6*8)+(5*4)+(4*3)+(3*7)+(2*3)+(1*3)=124
124 % 10 = 4
So 28437-33-4 is a valid CAS Registry Number.

, (2008/06/13)
Cyclisation substrates are disclosed of the formula: STR1 wherein: (a) R1 is H or alkyl of one to four carbon atoms; (b) R2 is H or alkyl of one to four carbon atoms, with the proviso that R1 is H when R2 is alkyl, and with the proviso that R2 is H when R1 is alkyl; (c) R3 is a suitable leaving group selected from the group consisting of hydroxy, alkoxy of one to four carbons, alkoxyalkoxy of two to four carbons, acyloxy of one to about seven carbon atoms, and trialkylsilyloxy of less than fifteen carbons; (d) R4 is methyl; and (e) R5(1) and R5(2) are each H, alkyl of one to eight carbons, or an optionally esterified or etherified hydroxy group selected from the group consisting of hydroxy, alkoxy of one to four carbons, alkoxyalkoxy of two to four carbons, trialkylsilyloxy of one to fifteen carbons, cycloalkoxy of four to eight carbons, carboxyacyloxy of one to seven carbons or heterocyclic ether of five to seven atoms and four to six carbons, with the proviso that at least one of R5(1) and R5(2) is hydrogen. A method is disclosed for the cyclisation of the compounds of formula I leading to compounds of the following formulae: STR2 having R4 and R5 (one of R5(1) and R5(2) that may or may not be hydrogen) as defined above, with R6 being alkyl of from one to about four carbon atoms.
