Check Digit Verification of cas no

The CAS Registry Mumber 121948-70-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,9,4 and 8 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 121948-70:
(8*1)+(7*2)+(6*1)+(5*9)+(4*4)+(3*8)+(2*7)+(1*0)=127
127 % 10 = 7
So 121948-70-7 is a valid CAS Registry Number.

Application of Dehydroabietic Acid in Palladium-Catalysed Enyne Cycloisomerisation

Wu, Na,Li, Ruikun,Cui, Feihu,Pan, Yingming

, p. 2442 - 2447 (2017)

Dehydroabietic acid (DAA) promotes palladium(0)-catalysed cyclisations of arene-tethered 1,7-enynols and 1,m-enynoates (m=6,7) to give fused carbocyclic dienes. 6,6,6,5-Tetracyclic lactones are accessible by one-pot cycloisomerisation/Diels–Alder reaction
