Check Digit Verification of cas no

The CAS Registry Mumber 1056020-06-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,5,6,0,2 and 0 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1056020-06:
(9*1)+(8*0)+(7*5)+(6*6)+(5*0)+(4*2)+(3*0)+(2*0)+(1*6)=94
94 % 10 = 4
So 1056020-06-4 is a valid CAS Registry Number.

One-pot synthesis of multifunctionalized m-terphenyls

Chang, Meng-Yang,Chan, Chieh-Kai,Lin, Shin-Ying,Wu, Ming-Hao

, p. 9616 - 9624 (2013/10/22)

A facile one-step synthetic protocol toward multifunctionalized m-terphenyls 5 and sulfonyl m-terphenyls 6 is developed from substituted chalcones 1 and allyl sulfone 2 in good yields via a [3C+3C] annulation. The NaH-mediated annulation features transition metal catalyst-free condition. Chalcones 1 with the functional groups tolerance are easily prepared via Claisen-Schmidt condensation of substituted benzaldehydes 3 with acetophenone 4 in a qualitative yield under an aqueous alkaline methanolic solution.
