Check Digit Verification of cas no

The CAS Registry Mumber 632620-65-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,2,6,2 and 0 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 632620-65:
(8*6)+(7*3)+(6*2)+(5*6)+(4*2)+(3*0)+(2*6)+(1*5)=136
136 % 10 = 6
So 632620-65-6 is a valid CAS Registry Number.

On the reaction of thiazole-2,4-diamines with isothiocyanates - Preparation and transformation of 2,4-diaminothiazole-5-carbothioamides

Hahnemann, Cornelia,Hartmann, Horst

, p. 1949 - 1965 (2007/10/03)

In the reaction of thiazole-2,4-diamines 8 with isothiocyanates 1, 2,4-diaminothiazole-5-carbothioamides 9, 10, 18, and 19 as well as thiazolo[4,5-d]pyrimidine-7(6H)-thiones 21 were formed. The carbothioamides 9, 10, and 18 were transformed by reaction with different types of monofunctional and bifunctional electrophiles into hitherto unknown acceptor-substituted 4,4′-([2,5′-bithiazole]-2′,4′-diyl)bis[morpholines] 24 and 29, the 2′,4′-bis(dialkylamino)[2,5′-bithiazol]-4-(5H)-ones 30, and the 4-substituted 2′,4′-bis(dialkylamino)-2,5′-bithiazoles 31. From 30 and 31 new 4-mono- or 4,5-disubstituted 2′,4′-bis(dialkylamino)-2,5′-bithiazoles 34, 35, 38, and 39 as well as 5-substituted 2′,4′- bis(dialkylamino)[2,5′-bithiazol]-4(5H)-ones 33, 36, and 37 were prepared.
