Check Digit Verification of cas no

The CAS Registry Mumber 874149-47-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,4,1,4 and 9 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 874149-47:
(8*8)+(7*7)+(6*4)+(5*1)+(4*4)+(3*9)+(2*4)+(1*7)=200
200 % 10 = 0
So 874149-47-0 is a valid CAS Registry Number.

[5C + 1S] annulation: A facile and efficient synthetic route toward functionalized 2,3-dihydrothiopyran-4-ones

Bi, Xihe,Dong, Dewen,Li, Yan,Liu, Qun,Zhang, Qian

, p. 10886 - 10889 (2007/10/03)

A facile and efficient synthetic route toward highly substituted 2,3-dihydrothiopyran-4-ones 2 has been developed via a formal [5C + 1S] annulation of readily available α-alkenoyl ketene-(S,S)-acetals 1 with sodium sulfide nonahydrated salt (Na2/sub
