Check Digit Verification of cas no

The CAS Registry Mumber 1309778-21-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,9,7,7 and 8 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1309778-21:
(9*1)+(8*3)+(7*0)+(6*9)+(5*7)+(4*7)+(3*8)+(2*2)+(1*1)=179
179 % 10 = 9
So 1309778-21-9 is a valid CAS Registry Number.

Rhodium-catalyzed carbene-transfer reactions via thienylcarbene complexes generated from thiocarbamoyl-ene-yne compounds

Tsuneishi, Asuka,Okamoto, Kazuhiro,Ikeda, Yuji,Murai, Masahito,Miki, Koji,Ohe, Kouichi

, p. 655 - 658 (2011)

Catalytic thienylcarbene-transfer reactions have been developed. The rhodium-catalyzed reaction of alkenes, furans, and thiophenes with a thiocarbamoyl-ene-yne compound as a carbene source gave the cyclopropanation products or ring-opened products of heterocycles. These processes provide efficient synthetic methods for thiophene-containing complex molecules. Georg Thieme Verlag Stuttgart - New York.
