Check Digit Verification of cas no

The CAS Registry Mumber 1038399-83-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,3,8,3,9 and 9 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1038399-83:
(9*1)+(8*0)+(7*3)+(6*8)+(5*3)+(4*9)+(3*9)+(2*8)+(1*3)=175
175 % 10 = 5
So 1038399-83-5 is a valid CAS Registry Number.

Regiospecific [2+2] cycloadditions of electron-poor acetylenes to (Z)-2-acylamino-3-dimethylaminopropenoates: synthesis of highly functionalised buta-1,3-dienes

Ur?i?, Uro?,Gro?elj, Uro?,Meden, Anton,Svete, Jurij,Stanovnik, Branko

, p. 3775 - 3778 (2008/09/21)

Microwave-assisted [2+2] cycloaddition reactions of 2-amino-3-dimethylaminopropenoates with acetylenecarboxylates furnished highly functionalised 1-amino-4-(dimethylamino)buta-1,3-dienes in 40-94% yields. All reactions were observed to consistently produce single geometrical isomers, and in cases where non-symmetrical acetylenes were employed the reactions proceeded in a regiospecific manner.
