Check Digit Verification of cas no

The CAS Registry Mumber 1422953-18-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,2,9,5 and 3 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1422953-18:
(9*1)+(8*4)+(7*2)+(6*2)+(5*9)+(4*5)+(3*3)+(2*1)+(1*8)=151
151 % 10 = 1
So 1422953-18-1 is a valid CAS Registry Number.

Total Synthesis of Gramistilbenoids A, B, and C

Harmalkar, Dipesh S.,Lu, Qili,Lee, Kyeong

, p. 798 - 805 (2018)

Stilbenes are biologically active metabolites of plants that have the potential to attenuate a broad range of human diseases. Gramistilbenoids are a class of natural products with a stilbene skeleton, isolated from the bamboo orchid (Arundina graminifolia), and with significant cytotoxicity against cancer cell lines (NB4, A549, SHSY5Y, PC3, and MCF7). These are the first identified naturally occurring diphenylethylenes to possess a hydroxyethyl unit. However, some of these compounds are not abundant in nature, and thus, their synthesis is advantageous. This paper reports the first synthesis of gramistilbenoids A (1), B (2), and C (3), with overall yields of 10, 2, and 8% respectively. These natural products were synthesized using key reactions, such as Horner-Wadsworth-Emmons olefination, Stille coupling, and hydroboration-oxidation.
