Check Digit Verification of cas no

The CAS Registry Mumber 1304145-72-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,4,1,4 and 5 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1304145-72:
(9*1)+(8*3)+(7*0)+(6*4)+(5*1)+(4*4)+(3*5)+(2*7)+(1*2)=109
109 % 10 = 9
So 1304145-72-9 is a valid CAS Registry Number.

Chiral br?nsted acids and their calcium salts in catalytic asymmetric mannich reactions of cyclic 1,3-diketones

Rueping, Magnus,Bootwicha, Teerawut,Sugiono, Erli

, p. 323 - 326 (2011)

Asymmetric calcium-catalyzed direct Mannich reactions of 1,3-dicarbonyl compounds with imines have been developed. The reactions proceed under mild conditions and provide the corresponding products with high enantiomeric excess. Georg Thieme Verlag Stuttgart New York.
